This document explains all the functions you can perform on objects only available in a BS2000 environment. It covers the following topics:
The BS2000 file maintenance facility enables you to perform functions on cataloged disk files of type SAM, ISAM and PAM, including LMS libraries. You can:
LIST,
COPY, RENAME and
DELETE all types of files, display
INFORMATION for them and
CHANGE file attributes;
ALLOCATE all types of files except
LMS libraries;
BROWSE,
EDIT, SUBMIT,
PRINT and EXPORT files of
type SAM and ISAM.
If the file consists of job control, you can make use of the Natural
ISPF macro facility. You can use all types of macro statements. Macro expansion
is performed at submission time (see the
SUBMIT
command below).
When creating a new file, you can also use the Edit macro feature to automatically create text lines which can then be modified. For details on the macro facility, see the section Macro Facility in the Natural ISPF Programmer's Guide).
To enter the BS2000 files maintenance facility
Select the BS2000 FILES option from the Natural
ISPF Main Menu.
The BS2000 Files Entry Panel appears:
------------------------ BS2000 FILES - ENTRY PANEL ---------------------------
COMMAND ===>
File Name ===> *
Volume ===> ( for selection list )
Password ===> ( If password protected )
Edit macro ===>
Shared file ===> ( for selection list )
More criteria ===> ( mark for special selection )
Node ===> 31
|
You can specify the file you wish to maintain in the input fields and enter a function command in the command line.
Meaning of the input fields:
| Field | Meaning |
|---|---|
File Name |
Displays the file name last used. You can select any other file by overtyping this name. Leave blank or use strings and wildcards (* and _) to generate a more selective list of files. See the subsection Selection Windows and Wildcards in the section Command Logic. |
Volume |
Volume serial number. Usually not needed, unless you want to restrict a list of files to those on a specific volume. |
Password |
System password if file is protected. Must be specified irrespective of read or write protection. |
Edit macro |
Name of macro object to be used as a model for the file.
The specified macro is executed and loaded into the Editor. See the section
Macro Facility
in the Natural ISPF Programmer's Guide for details. When
used with LIST, the list contains all files
according to the name criteria that use the specified macro as a model.
|
Shared file |
Enter YES to restrict the
LIST function to shared (public) files or
NO to restrict it to non-shared files.
|
More criteria |
Option. Can be marked with any character to open a
window where additional criteria for LIST selection
can be specified. See the corresponding subsection.
|
Node |
Select Entire System Server node. Enter a question mark
(?) and press ENTER to open a window in which all node numbers are
scrolled with an ACTIVE or INACTIVE status report. If
you do not specify a node, the default node indicated on the Main Menu is
assumed.
|
Apart from the input fields listed above, some parameters of the
LIST command are supported which do not correspond
to an input field of the panel, but which can be specified either by direct
command syntax (see below) or by means of the More
criteria option:
------------------------ BS2000 FILES - ENTRY PANEL --------------------------- COMMAND ===> +-------------------------Options for LIST-BS2FILE:-------------------------+ ! ! !

Support Type |
Select BS2000 files that reside on a specific storage medium. If you omit this parameter, or if you enter the asterisk wildcard (*), all kinds of files are selected, including tape files. Valid options are: **
|
Access Type |
Select BS2000 files that are - or are not - protected against modification. Valid options are: **
|
FGGs only |
Mark this field with any non-blank character if only file generation groups and the related individual generations are to be selected and included in the resulting list of BS2000 files. |
Unclosed only |
Mark this field with any non-blank character if you want the resulting list of BS2000 files to contain only files that were opened for output (write, extend or update) and that have not yet been closed. |
FCBType |
Select BS2000 files that correspond to
one or more file organization attributes (SAM, PAM, ISAM, NONE or combination).
To select for a combination, concatenate the first characters of the requested
attributes to form a string, for example: PI for PAM and
ISAM)
|
* Fields not mentioned here (File Name,
Volume, Shared File and Node) contain
the values specified in the corresponding fields of the BS2000 Files Entry
Panel and have the same meaning as described above.
** Options can be abbreviated.
| Field | Meaning |
|---|---|
Passw. security |
Fill in the appropriate specification if you want the resulting list of BS2000 files to contain only files that are (or are not) password protected. Possible values:
Combinations of the above values can also be specified as selection criteria simply by concatenating the value abbreviations. Examples: |
Range keyword |
The range options listed below narrow down a list of files. To use one of these, enter one of the following abbreviations:
Note: If you specify one of these options, you must specify the corresponding range itself (either single value or list of values) in the Range value field below. |
Range value |
Use this field to specify:
The format of this specification depends on the Range
option entered in the previous field and is identical to the notation used with
a BS2000 Examples: Range keyword: Range value:

1 For the CHANGE command,
see also the subsection Changing the Attributes of
a BS2000 File.
2 Enter only one of the parameters enclosed in brackets
< >. For the LIST command, see also the
subsection Listing BS2000
Files.
A full description of these commands is contained in the section
Command
Reference. For all function commands except
LIST and CHANGE, the
object parameters correspond to the input fields on the BS2000 Files Entry
Panel.
Notes:
BF before the object parameters.
RECLEN parameter can be specified on the
EDIT command to reduce storage requirements. For
example, you can specify RECLEN=80 if you issue an
EDIT command for a file with record format V which
does not contain lines that exceed length 80. If you omit the
RECLEN parameter, the value from the catalog information
is assumed, if available. Otherwise, the maximum line length for
BROWSE or EDIT sessions
is taken, that is, 253.
ALLOCATE command applies only
to non-standard files. A file with standard attributes (that is, SAM files with
record format V) is automatically allocated simply by starting an edit session
and issuing the SAVE command. The
ALLOCATE command also applies to LMS libraries. LMS
libraries can be allocated using the COPY command
(for example, copy an empty library) or the ALLOCATE
command.
LIST, if
you do not specify the full file name, but only a prefix followed by the
asterisk wildcard (*), a selection window opens that lists the existing files
which start with that prefix. If you specify only the asterisk wildcard (*) as
file name without a prefix, the selection window lists file names for which
short IDs are defined, that is, in this case the selection is based on profile
definitions rather than on catalog information (see the subsection
Library Definition
in the section Profile Maintenance). In both kinds of
selection window, you can select a file for further processing by marking it
with any character and pressing ENTER.
Lists of BS2000 files can be generated using the
LIST command and selection criteria in the parameter
input fields of the BS2000 Files Entry Panel. Alternatively, you can issue the
LIST command with appropriate parameters from any
system screen. In the FILE-NAME parameter, you can optionally
specify a catalog ID and/or a user ID. This lists shared files only. If you
omit the catalog ID / user ID specification, or if you specify the current user
ID, all files for which the user ID is authorized are listed.
Notes:
Descriptive parameters can be specified with usual keyword syntax.
The keyword parameters SHARE and
VOLSER correspond to the fields on the BS2000 Files Entry Panel
(see above).
The keyword parameters ACCESS,
SUPPORT and FCBTYPE correspond to
the fields on the More criteria options screen; the keyword parameter
STATE corresponds to the field Unclosed only on that
screen. Specify STATE=NOCLOSE to restrict the list to files that
were opened for output (WRITE,
EXTEND or UPDATE) and
have not yet been closed.
The keyword parameter SIZE can be
used to select BS2000 files with space allocation (number of PAM pages)
corresponding to the given value or range of values. A range must be specified
as (n:m),
for example: (24:999). If only one of the boundaries n and m is
relevant, you can omit the other.
The keyword parameter CREATION can be
used to select BS2000 files that were created (or updated) on a specific day,
or within a range of days. A range must be specified as
(from:to).
If only one of the boundaries
(from or
to) is relevant, you can omit the other
one. The boundaries, as well as a specific day, can both be specified in one of
the following notations:
| Notation | Description |
|---|---|
YYYY-MM-DD |
Long date notation |
YYMMDD |
Short date notation |
-n |
Relative date notation |
T or
TODAY |
(relative to the current day) Current day |
Y or
YESTERDAY |
Previous day |
The keyword parameter LAST-ACCESS can
be used to select BS2000 files that were last accessed on a specific day, or
within a range of days. The syntax conventions for specifying the day or time
range are the same as for CREATION.
The keyword parameters SIZE,
CREATION and LAST-ACCESS are
mutually exclusive, that is, these must not occur in the same command.
Below are some examples of the LIST
function commands using full command syntax.
LIST BF ADA*
lists all files starting with ADA owned by
current user ID.
LIST BF $DEMO.*ADA*
lists all public files owned by user ID DEMO
that have ADA as part of their name.
LIST BF :K:$DEMO.*
lists all public files in catalog K owned by
user ID DEMO.
LIST BF *LIS* LAST-ACCESS=(940601:940930)
lists all files owned by current user ID with string
LIS occurring as part of the file name, and last accessed within
the specified period.
LIST BF $DEMO.* NODE=38
lists all public files owned by user ID DEMO on
Entire System Server Node 38 in a multi-node environment.
An example of a list of BS2000 files follows.
The following figure shows an example of a list of BS2000 files generated using the command:
LIST BF :NAT:$ABC.*TEST*
The list generated shows all public files owned by user ID
ABC in catalog NAT that have the string
TEST in their names:
LIST-BF:(125)*TEST* ----------------------------- Row 0 of 37 - Columns 056 076 COMMAND===> SCROLL===> PAGE PATH-NAME OF FILE PAM-PAGES M ** ******************************** top of list ******************************* :NAT:$ABC.D.TEST.JOBLIB 0000005475 2 :NAT:$ABC.D.TEST.NPR.JOBLIB 0000004800 2 :NAT:$ABC.D.TEST.PAM 0000000450 2 :NAT:$ABC.D.TEST.SAM 0000000192 2 :NAT:$ABC.E.ISP.TEST 0000000003 2 :NAT:$ABC.E.TEST.NPR.SPOOL 0000000003 2 |
Use the RIGHT command (usually assigned to PF11) to scroll right in order to display more information:

Full path name including catalog ID and user ID specification. |
PAM-PAGES |
Number of disc pages allocated for the file. |
MODIF-DATE |
Date when the file was last modified. |
TIME |
Time when the file was last modified. |
The session header reflects the path name pattern used for
selection and, optionally, additional criteria specified by means of function
command syntax in the BS2000 Files Entry Panel or in the
LIST options window. If this information does not
fit into a screen line, it is truncated.
LIST-BF:*LIB*/LAST=(940601:940930) ----------- Row 0 of 2 - Columns 056 071
You select a file from a list by typing in a line command in the input field preceding the file name and pressing ENTER. Each line command is an abbreviation of a function command.
| Line Command | Function Command | Meaning |
|---|---|---|
A |
ALLOCATE |
Allocate a new file. The attributes of the selected file are displayed, which you can modify for the new file. |
B |
BROWSE |
Display sequential file (SAM or ISAM). No modification is possible. |
CH |
CHANGE |
Change attributes of file, for example, define a password. |
CP |

SB |
SUBMIT |
Submit the file (an ENTER job; if applicable, after macro expansion). |
Line commands can also be used as valid abbreviations of function commands entered in the command line of any system screen.
If you display a file in Editor format, you can issue some local commands from the Editor command line in addition to Editor commands.
The following local commands are available.
| Command | Meaning |
|---|---|
IMPORT |
Imports a PC file or Con-nect document into the file (see the section Useful Features). |
PASSWORD
password |
If the file is password-protected,
use this command to enter the valid password in order to update the file. If
you enter the PASSWORD command without parameter, a
window prompts you for the password. Password input in the window is
invisible.
|
REGENERATE |
Available for files written using the Edit macro option. Reexecutes the specified macro object and writes the result in protected lines in the current edit session. Any defined user code remains in place. For details, see the section Macro Facility in the Natural ISPF Programmer's Guide. |
If you display lists of BS2000 files in Editor format, you can
issue the following local commands in addition to Editor scroll commands:
ALL, LAYOUT,
RELIST and SORT. For
detailed information, see the corresponding subsections in the section
Useful Features.
The CHANGE function command allows you
to modify attributes of a file that are stored in the system catalog. You can
specify one or more new attribute values as function parameters, using keyword
parameter syntax (see Example 3).
If you issue the CHANGE command with or
without object parameters, but without any function parameters, or if you issue
the line command CH from a list of files, a window
opens that displays the current attribute values, except for passwords. To
modify one or more attributes, overtype the values in the input fields and
press ENTER.
The following window opens if you enter the command:

Meaning of the input fields:
| Field | Meaning |
|---|---|
SHARED FILE - SHARE |
Enter Y or YES to make the
file accessible to other users. Enter N or NO to
restrict access to the owner user ID.
|
ACCESS-TYPE - ACCESS |
Enter W or WRITE to allow
write access to the specified file, which also implicitly includes
authorization for read access. Enter R or READ to
allow read access only.
|
RETENTION-PERIOD - RETPD |
Enter a number representing a retention period (in days) that is to be assigned to the specified file: This means it can neither be modified nor deleted within the specified period of time. |
READ-PASSWORD - READPSWD |
Enter a password to protect the file against
unauthorized read accesses. Enter *NONE to reset an existing
password, provided that you specified that password together with the current
CHANGE function.
|
WRITE-PASSWORD - WRITEPSWD |
Enter a password to protect the file against
unauthorized modification or deletion. Enter *NONE to reset an
existing password, provided that you specified that password together with the
current function.
|
EXEC-PASSWORD - EXECPSWD |
Enter a password to protect the file against
unauthorized execution; this applies to procedure files and load modules. Enter
*NONE to reset an existing password, provided that you specified
that password together with the current CHANGE
function.
|
BACKUP-TYPE - BACKUP |
Enter a backup class to be assigned to the specified
file, thus controlling how the file is to be handled by (periodic) runs of the
|
#BACK-VERS - BACK-VERS |
Enter a value from 0-32 for the maximum
number of file versions to be stored in the version backup archive. Entering
the value 0 is the equivalent of ignoring the version backup, as
no file versions will be stored then.
|
If the file you wish to maintain is password-protected, correct
password specification is also required for the
CHANGE command. For example, if you enter the
command:
CHANGE BF T.TEST PASSW=HUGO
the following window opens:

Enter *NONE to reset the password.
To avoid visible input of the old password on your screen, issue
the CHANGE command from the BS2000 Files Entry Panel
and specify the password in the corresponding input field of the
CHANGE window.
To avoid being prompted for the new attribute values (for example, during a batch run or during execution of a command script), specify them as function parameters using the keywords indicated above. For example, the command:
CH BF DEMO.PHASE, ACCESS=READ BACKUP=E
inhibits modification of the file DEMO.PHASE and
assigns backup type E, that is, the file is not saved
automatically with any periodic ARCHIVE run.
When you save a BS2000 file, Natural ISPF checks if the file has
been modified by another user or another session while you were editing. If
this is the case, you are notified by a message and the
SAVE operation is not executed. However, this check
can only be performed if Version 11 (OSD V1) or higher of BS2000 is installed
at your site. For lower versions of BS2000, Natural ISPF does not check for
concurrent editing. If your SAVE operation is
rejected due to concurrent editing, you can use the
BROWSE command to inspect the file and you can
decide whether to override it with your latest modifications or not. To
override it, you can either:
use the REPLACE command for the
existing file, or
delete the existing file and then save the version with your latest changes.
The BS2000 LMS library elements maintenance facility allows you to perform functions on elements of LMS programming libraries.
If the element consists of job control, you can make use of the
Natural ISPF macro facility. You can use all types of macro statements. Macro
expansion is performed at submission time (see the
SUBMIT
command below). When creating a new element, you can also use the Edit macro
feature to automatically create text lines which can then be modified. For
details on the macro facility, see the section
Macro Facility
in the Natural ISPF Programmer's Guide).
To enter the LMS element maintenance facility
Select the LMS option from the Natural ISPF Main
Menu.

You can specify the element you wish to maintain in the input fields and enter a function command in the command line.
Meaning of the input fields:
| Field | Meaning |
|---|---|
File Name |
Displays the file name last used. You can select any
other file by overtyping this name. Leave blank or use strings and wildcards (*
and _) to generate a more selective list of PAM files. See the subsection
Selection Windows and
Wildcards in the section Command Logic.
When requesting a list of files, the command is automatically transferred to
object type BF (see the subsection
BS2000
Files).
|
Element |
Name of the required element in the specified file.
Leave blank or use selection criteria as described for the File
Name field to generate a list of elements. If more than one version
exists for an element, the highest version is listed.
|
Type |
Type of required element. This is optional if the
element name is unique. If you are creating a new element and omit this field,
type S (source) or the value from your profile is taken as
default. When listing elements, combinations of type notation are possible, for
example, JD for jobs and data elements.
|
Version |
You can specify a previous version of the element in this field. If this is omitted, either the highest version is selected, or a version according to the value in your user profile (default is the highest possible version, indicated by the character §, or the character that corresponds to hexadecimal 7C) . |
Record length |
This must be specified if the actual record length exceeds the default length according to element type. The defaults are:
|
Password |
System password if library or element is protected. Must be specified irrespective of read or write protection. |
Scan for |
Lists elements which contain the string specified here.
When you select a member from this list for EDIT or
BROWSE, the cursor is placed on the first occurrence
of this string in the element. Issue the RFIND
command to find the next occurrence.
|
Edit macro |
Name of macro object to be used as a model for the new
element. The specified macro is executed and loaded into the Editor. See the
section Macro
Facility in the Natural ISPF Programmer's
Guide for details. When used with LIST,
the list contains all elements according to the name criteria that use the
specified macro as a model.
|
Node |
Select Entire System Server node. Enter a question mark
(?) and press ENTER to open a window in which all node numbers are
scrolled with an ACTIVE or
INACTIVE status report. If you do not specify a
node, the default node indicated on the Main Menu is assumed.

A full description of these commands is contained in the section Command Reference. The object parameters correspond to the input fields on the LMS Elements Entry Panel.
If you issue any of the above function commands from outside the LMS elements facility, you must specify the object-type parameter LMS before the object parameters.
The file-name parameter is optional, Natural ISPF then takes the current file name, or if you issue a command from outside the LMS elements facility, from your profile.
Instead of typing the keywords TYPE and
VERSION when specifying an element, the following notations are
valid:
FILENAME(ELNAME)T/VVVVV FILENAME(element-selection) element-selection /* Current file name is assumed
where element-selection can be any of the following:
(T)ELNAME/VVVVV ELNAME/VVVVV(TTT) ELNAME/VVVVV
Note that TTT represents a string of valid element
types when requesting a list of elements. The version notation
(/VVVVV) is required only when selecting a version other than the
highest one.
Lists of elements in an LMS-type library can be generated using
the LIST command and selection criteria in the
parameter input fields of the LMS Elements Entry Panel. Alternatively, you can
issue the LIST command with appropriate parameters
from any system screen. The list can be restricted to selected elements by
specifying certain selection criteria:
Element name prefix or pattern using wildcards (* and _);
Element type or multiple types;
Specific element version;
Scan value, listing only those elements that contain the specified string;
Model name, listing only those elements that were generated by the specified Edit macro.
Below are some examples of the LIST
function commands using full command syntax.
LIST LMS $DEMO.DEMOLIB(*OC*)
lists all elements in the specified library that have the
string OC in their name.
LIST LMS $DEMO.DEMOLIB(ED*) TYPE=SM
lists elements in the specified library with names starting
with ED; only S (source) and M (macro)
type elements are listed.
LIST LMS $DEMO.DEMOLIB(*/120) TYPE=D
lists all library elements of Type D that have
Version Name 120 assigned.
LIST LMS $DEMO.DEMOLIB(E.*) SCAN=EXAMPLE
lists all library elements that start with E.
and which contain the string EXAMPLE.
LIST LMS $DEMO.DEMOLIB(E.*) MODEL=EXB5
lists all library elements that start with E.

ELEMENT-NAME |
Name of element |
NUM |
Number of occurrences of the scan string in the highest version |
FIRST FOUND |
First occurrence of the scan string in the highest version. |
You select an element from a list by typing in a line command in
the input field preceding the element name and pressing ENTER. Each
line command is an abbreviation of a function command (but see the special
LIST line command for an element):
| Line Command | Function | Meaning |
|---|---|---|
B |
BROWSE |
Display element. Not available for Type
C. No modification is possible.
|
CP |
COPY |
Copy the element into another object (target object type and name will be prompted). |
D |
DELETE |
Erase the element from the library. Note that all versions are deleted. |
E |
EDIT |
Edit the element. Not available for types
C and R. Elements stored in Delta mode cannot be
updated (the SAVE command is rejected).
|
EX |
EXPORT |
Export element to external environment (PC or Con-nect). Not available for type C. |
L |
LIST |
List all versions of the element. See the subsection Versions of LMS Elements below. |
PL |
PLAY |
Run the element as a Natural ISPF command script. Not
available for Types C and R.
|
PR |
PRINT |
Create a report of element. Not available for Type
C.
|
R |
RENAME |
Rename the element (not available for elements stored in Delta mode). Note that all versions are renamed. |
SB |
SUBMIT |
Submit the element (an ENTER job; if
applicable, after macro expansion). Only available for Type
J.
|
Line commands can also be used as valid abbreviations of function commands entered in the command line of any system screen.
If you display an LMS element in Editor format, you can issue some local commands from the Editor command line in addition to Editor commands.
The following local commands are available:
| Command | Meaning |
|---|---|
IMPORT |
Imports a PC file or Con-nect document into the element (see the section Useful Features). |
NEWNAME
elname/version |
Specifies a new element name and/or version name to
be used on subsequent SAVE operations. If you enter
the NEWNAME command without parameters, a window
prompts you for the new element and version name(s).
|
PASSWORD
password |
If either the library or the edited element is
password-protected, use this command to enter the valid password in order to
update the element. If you enter the PASSWORD
command without parameter, a window prompts you for the password. Password
input in the window is invisible.
|
REGENERATE |
Available for elements written using the Edit macro option. Reexecutes the specified macro object and writes the result in protected lines in the current edit session. Any defined user code remains in place. For details, see the section Macro Facility in the Natural ISPF Programmer's Guide. |
You may find it useful to define the greater than character
(>) as a magic character in your user profile and assign it to the command
;NEWNAME_. This allows you to use a direct command
notation very similar to the command syntax of LMS when used in a TIAM dialog
session. For example:
EDIT (D)DOCTX/002>DOCU-NEW
opens an edit session on data element DOCU-NEW,
filled with the contents of data element DOCTX, version
002. The new element will have the same version identification
002 assigned.
E $VG.CVRP(CVPROT)>/V-TEST
opens a session with element CVPROT of any type
(provided this element exists and is of unique type) in library
$VG.CVRP. Data is read from the highest version encountered and is
saved as version V-TEST.
If you display lists of LMS elements in Editor format, you can
issue the following local commands in addition to Editor scroll commands:
ALL, LAYOUT,
RELIST and SORT. For
detailed information, see the corresponding subsections in the section
Useful Features.
When you save an LMS library element, Natural ISPF checks if the
same element has been modified by another user or another session while you
were editing. If this is the case, you are notified by a message and the
SAVE operation is not executed. You can use the
BROWSE command to inspect the element and you can
decide whether to override it with your latest modifications or not. To
override it, you can either:
use the REPLACE command for the
existing element, or
delete the existing LMS element and then save the version with your latest changes.
Previous versions of LMS elements can be kept and retrieved using Natural ISPF. The way versioning is done for LMS elements is slightly different from objects on other platforms, therefore most of the information given in the subsection Versioning in the section Useful Features does not apply.
You can list previous versions of an LMS element by either:
Issuing the LIST function command
from any system screen, specifying the library and element selection criteria
in the command syntax (note the version and type selection criteria described
in the subsection Function
Commands above), or:
Selecting an element from a list of elements using the
L line command.
LIST LMS $DEMO.DEMOLIB(E.EXAM/*)
lists all versions of the specified library element.
LIST LMS $DEMO.DEMOLIB(EXAMPLE/*N*) TYPE=S
lists those versions of source-type element
EXAMPLE that have the letter N in their names. The
TYPE parameter is required only if the element name
EXAMPLE is not unique in the library (for example, if an element
EXAMPLE of Type J is contained in the same library).
LIST LMS $DEMO.DEMOLIB(EXAMPLE) VERSION=V* SCAN=EXAM
lists those versions of library element EXAMPLE
whose names start with V and which contain the string
EXAM.
The following screen shows an example of a list of library element versions. The function command used to generate the list was:
LIST LMS :D:$ASF.ASF.LMSLIB(ASFSW)R/*
The list displays all versions of the element ASFSW
in the specified library:

A number of functions can be performed on versions of LMS elements. A version can be selected in either of the following ways:
Select a version by entering a line command in the input field preceding the version name in the list of element versions;
Perform the function from any system screen by issuing a
function command directed at object type LMV, identifying the version by
library name, element name, and version name. The TYPE
parameter is required only if the element name is not unique in the library.
Line commands can also be used as abbreviations of function commands in command syntax. Available functions for LMS element versions are:
| Line Command | Function | Meaning |
|---|---|---|
B |
BROWSE |
Display element version. Not available for Type

Other Natural ISPF objects such as Natural programs or PDS members can be updated in place (with versioning disabled), or continuous versioning can be in effect for each update. In contrast, LMS elements kept in Full Storage Mode can be updated in place, even if there already are several versions of the element being updated. Additionally, for LMS elements in Full Storage Mode, no version identifier is automatically assigned. This means that every time you are about to update an LMS element, you can decide whether you wish to keep the current version or not, and if you do, you can specify a name for the new version according to your site's naming conventions.
Specifically, if you intend to update a certain LMS element and wish to keep the current version, you can proceed in any of the following ways:
Start an edit session with the current version, for example,
by selecting it from a list of LMS elements with the
E line command. Modify the data and use the
NEWNAME local command to assign a new name to the
version. This version is stored with the SAVE
command, or when the session is ended (provided AUTOSAVE=ON is
specified in your user profile).
If the LMS Override option has been set to * in
your BS2000 Defaults profile, a prompt window opens every time you save an LMS
element or an existing element version. This window allows you to either assign
a new version name, if a new version is to be created, or confirm that the
modified version is overwritten (that is, updated in place, option
YES):

If the LMS Override option is set to NO in your
BS2000 Defaults profile, a similar prompt window to the one in the above
example is opened when you wish to save an existing element. In this window,
however, you are not offered the option of overriding the old version.
Start an edit session with the current version, for example,
by selecting it from a list of LMS elements with the
E line command. Modify the data and issue the
RENAME command without any parameters. A window
opens in which you can specify a version name to be assigned to the previous
version. When you store the modified version (with the
SAVE command, or END with
AUTOSAVE=ON), the new version will have the same version name as
the previous version before it was modified. This method is recommended if you
always wish to carry over the same name to the current version. This is
particularly useful to retain version name § (or the character
that corresponds to hexadecimal 7C), which always denotes the highest version
with respect to the LMS internal sort sequence.
As an alternative to the prompt window, you can use the full
RENAME function command syntax in the command line
of the edit session with the LMS element. Issue either:
RENAME,VERSION=vname
or:
RENAME, /vname
where vname is the version name to be assigned to the previous version.
Notes:
The job information facility allows you to display information about BS2000 jobs (tasks). You can also use this facility to handle files related to a specific job.
To enter the job information facility

The function command CC provides an
overview of job variables related to a specific job. It lists the variable
names and the first 64 bytes of their values. The criteria for selecting the
variables are as follows:
job variables containing the TSN of the job as part of their names, enclosed in periods (.);
job variables containing the TSN at any position in their value;
if the specified job was the last job created by the Natural
ISPF SUBMIT function, and if a monitoring job
variable was specified when submitting, that monitoring job variable is
included;
only job variables of the current BS2000 user ID are selected.
Notes:
CC function command is
available only if SNI's software product JV has been installed as part of your
BS2000 system environment.
The BS2000 job variables facility provides functions that include
LIST, EDIT,
RENAME and DELETE job
variables. You can also display information on a specific job variable,
including its attributes and (if you are authorized to read it) its value. You
can create a new job variable with standard attributes simply by editing and
saving it, and you can modify the attributes of a job variable using the
function command CHANGE.
All functionality described in this section is available only if SNI's software product JV has been installed as part of your BS2000 system environment.

Note:
If you issue any of the above function commands from outside
the job variables facility, you must specify the object-type parameter
JV before the object parameters.
A full description of these commands is contained in the section Command Reference. The object parameters correspond to the input fields on the BS2000 Job Variables Entry Panel.
The specification can optionally contain a catalog ID and a different user ID. If so, only shared job variables are listed. If catalog ID and user ID are omitted, or if the specified user ID is identical to the current one, the list contains all job variables owned by the current user ID that fit into the path name pattern.
Notes:
LIST JV ASM*
lists all job variables with prefix ASM and owned by the current user ID.
LIST JV $DEMO.*ASM*

("condition codes") of a specific BS2000 job (see the subsection
Condition Codes of BS2000
Jobs); in this case, the list also contains the first
characters of the values stored in the job variables listed.
Meaning of column headings:
| Column | Meaning |
|---|---|
PATH-NAME |
Full path name including catalog ID and user ID specification |
CONTENT |
First 64 bytes of job variable value
(CC-type lists only)
|
Select a job variable from a list by typing in a line command in the input field preceding the path name and pressing ENTER. Each line command is an abbreviation of a function command. Line commands can also be used as valid abbreviations of function commands entered in the command line.
Available line commands are:
| Line Command | Function | Meaning |
|---|---|---|
CH |
CHANGE |
Change attributes of job variable, for example, define a password. |
D |
DELETE |
Erase job variable from system. |
E |
EDIT |
Start editing job variable, in order to modify its contents or to use cross-copy operations. |
I |
INFORM |
Show attributes and full contents of job variable. |
R |
RENAME |
Rename the job variable. |
If you display a job variable in Editor format in
EDIT mode, the following local command is available
in addition to Editor commands:
| Command | Meaning |
|---|---|
PASSWORD
password |
If the job variable is
password-protected, use this command to enter the valid password in order to
update the variable. If you enter the PASSWORD
command without parameter, a window prompts you for the password. Password
input in the window is invisible.
|
If you display lists of job variables in Editor format, you can
issue the following local commands in addition to Editor scroll commands:
ALL, LAYOUT,
RELIST and SORT. For
detailed information, see the corresponding subsections of the section
Useful Features.
An information screen similar to the following appears as a result of the command:
INFORMATION JV $DC1.TEMP
------------------------- JOB VARIABLE INFORMATION ----------------------------
COMMAND ===>
JOB VARIABLE NAME: $DC1.TEMP

065-128: M133.FUSER,DEV=T9G,VOL=NOM133,FSEQ=3
|
This screen displays current attributes of job variable
$DC1.TEMP. Its current value is also displayed, if you are
authorized to read it; otherwise the subsection titled CURRENT
CONTENTS is omitted without notice. The data displayed are
self-explanatory.
There are two local commands available from this screen:
| Local Command | Meaning |
|---|---|
PASSWORD
password |
Supplies the correct password for
read access, in order to display the subsection CURRENT CONTENTS.
If you enter the PASSWORD command without parameter,
a window prompts you for the password. Password input in the window is
invisible.
|
REFRESH |
Reevaluates data to display latest attributes. |
When a job variable is edited, its contents are read into a single line of an edit session. A screen appears similar to the following:
EDIT-JV:$DC1.TEMP --------------------------------------------- Columns 001 072
COMMAND===> SCROLL===> CSR
=cols ----+----1----+----2----+----3----+----4----+----5----+----6----+----7--

Use the Editor commands RIGHT and
LEFT (usually assigned to PF11 and
PF10 respectively) to scroll horizontally (the length of the line is
restricted to 256 characters).
You can create more than one line of edited data temporarily (this
can be useful during complex editing operations), but the
SAVE command is rejected if the session contains
more than one line of data.
The CHANGE function command enables you
to modify attributes of a job variable. You can specify one or more new
attribute values as function parameters, using keyword parameters (see Example
3).
If you issue the CHANGE command with or
without object parameters, but without any function parameters or if you issue
the line command CH from a list of job variables, a
window opens that displays the current attribute values, except for passwords.
To modify one or more attributes, overtype the values in the input fields and
press ENTER.
The following window opens if you enter the command:
CHANGE JV MY.STANDARD.JVAR
-------------------- BS2000 JOB VARIABLES - ENTRY PANEL -----------------------
COMMAND ===> CHANGE JV MY.STANDARD.JVAR

Meaning of the input fields:
| Field | Keyword | Meaning |
|---|---|---|
SHARED JOB-VARIABLE |
SHARE |
Enter Y or YES to make the
job variable accessible to other users. Enter N or NO
to restrict access to the owner user ID.
|
ACCESS-TYPE |
ACCESS |
Enter W or WRITE to allow
write access to the specified job variable, which also implicitly includes
authorization for read access. Enter R or READ to
allow read access only.
|
RETENTION-PERIOD |
RETPD |
Enter a number representing a retention period (in days) that is to be assigned to the specified job variable: This means it can neither be modified nor deleted within the specified period of time. |
READ-PASSWORD |
READPSWD |
Enter a password to protect the job variable against
unauthorized read accesses. Enter *NONE to reset an existing
password, provided that you specified that password together with the current
CHANGE function.
|
WRITE-PASSWORD |
WRITEPSWD |
Enter a password to protect the job variable against
unauthorized modification or deletion. Enter *NONE to reset an
existing password, provided that you specified that password together with the
current function.
|
If the job variable to be changed is password-protected, you must also correctly specify the password. For example, the following window opens if you issue the command:
CHANGE JV JV.MIDI.2PTG PASSW=BOBO
-------------------- BS2000 JOB VARIABLES - ENTRY PANEL -----------------------
COMMAND ===> CHANGE JV JV.MIDI.2PTG PASSW=BOBO

Enter *NONE to reset the password.
To avoid visible input of the old password on your screen, issue
the CHANGE command from the BS2000 Files Entry Panel
and specify the password in the corresponding input field of the
CHANGE window.
To avoid being prompted for the new attribute values (for example, during execution of a command script), specify them as function parameters using the keywords indicated above. For example, the command:
CH JV PARMJV, SHARE=Y WRITEPSWD=BOHR
makes the job variable PARMJV shared, that is
accessible by other users, and protects it against unauthorized modification.
A console display is available for BS2000 environments. For a description, see the subsection Console Display in the section z/OS Objects.
