Options

In place of options, you may specify one of the options shown below.

[[WITH] DIRECTORY] [NUMBERS OFF] [expand-option]

formatted-option
CONVERTED
DIRECTORY This option first displays the directory information (as described below, see Displaying Directory Information) on the specified object and then lists the source code of the object.
NUMBERS OFF By default, the source code of an object will be listed with source-code line numbers. To list it without line numbers, specify the NUMBERS OFF option. (See also subcommands NUMBERS ON/NUMBERS OFF in the section Subcommands for Listed Source.)
CONVERTED By default, the source is listed in the code page as stored on the system file. To list the source in the default code page (see system variable *CODEPAGE), specify this option.

expand-option

EXPAND [ FORMATTED]

COMMENTS

[expand-type ...10]

object-name object-name-range

n
EXPAND object-name

With the EXPAND option, you can have the sources of other objects referenced by the listed object - copycodes, data areas, maps, helproutines, external subroutines, subprograms, programs called with a FETCH statement, error messages - listed within the source of the listed object. This option is particularly useful in batch mode.

For example, if a listed source program contains an INCLUDE statement, you can have the source code of the included copycode listed within the listed source program immediately after the INCLUDE statement.

Objects listed within a source will be referred to as "expand objects" in the explanations below.

Subcommands in Expand Object

Within a listed expand object, only the following subcommands are available:

PRINT
+
- -
.

See Examples of List of Objects Usage.

EXPAND object-name-range
EXPAND FORMATTED

The EXPAND FORMATTED option is only relevant for stowed data areas (where time stamp of source object and cataloged object are identical) and maps listed within a source.

For data areas, the following applies:

  • If FORMATTED is not specified, the display of the data area will resemble that in the data area editor

  • If FORMATTED is specified, the display of the data area will resemble a DEFINE DATA statement. This only applies to stowed data areas (i.e. the time stamp of source object and cataloged object are identical); see also subcommand FORMAT.

For maps, the following applies:

  • If FORMATTED is not specified, the map source will be listed.

  • If FORMATTED is specified, the map layout will be displayed (that is, the map as it is displayed to the users at runtime).

EXPAND COMMENTS

If you use the option EXPAND COMMENTS, only the initial comment lines of the expand object will be listed; that is, the expand object will be listed until (but not including) the first source-code line which is not a comment line.

If you use the option EXPAND n, only the first n lines of the expand object will be listed.

If you use neither of these two options, the entire expand object will be listed.

EXPAND n
expand-type

As expand-type, you specify the object type(s) of the expand object(s). The following expand-types can be specified:

P Programs If you wish to specify more than one expand-type, you can specify them in any sequence and without blanks between them; for example, to have maps, copycodes and subroutines listed within the listed source, specify the expand-type as MCS.
N Subprograms
S External subroutines
H Helproutines
G Global data areas
L Local data areas
A Parameter data areas
M Maps
C Copycodes
E Error messages
4 Classes
* All object types
object-name

As object-name or object-name-range, you specify the name(s) of the expand object(s) to be listed within the main listed source.

The same notations are possible as for object-name or object-name-range, except < and >.

FORMATTED Option

The FORMATTED option applies to stowed data areas (where time stamp of source object and cataloged object are identical) and maps:

FORMATTED
Stowed Data Area:

If you specify the FORMATTED option for a data area, the data area will be displayed formatted; that is, the display resembles a DEFINE DATA statement; see also subcommand FORMAT.

This only applies to stowed data areas (i.e. the time stamp of source object and cataloged object are identical). By default, data areas are displayed unformatted; that is, the display resembles that in the data area editor.

The default setting can be changed with in the List Profile. (Refer to Defining an Individual List Profile below and see also subcommand FORMAT).

Map:

If you specify the FORMATTED option for a map, the map layout will be displayed; that is, the map as it is displayed to the users at runtime.

FORMATTED Options for Listing Maps

When you are listing maps, you may specify options in addition to the keyword FORMATTED:

['c'] ['c']
Using Filler Characters:
You may specify filler characters c for input fields (AD=A and AD=M) and output fields (AD=O) to make these fields visible. You may specify any character as filler character.

The following example shows all input fields with an underscore (_) and all output fields with a hash (#).

LIST MAP map-name FORMATTED '_' '#'

Diplaying Processing Rules for a Map

The following options cause the processing rules used by the map to be displayed. The rules are displayed in order of fields to which they are assigned, and per field in order of rank.

RULES
All Rules:
LIST MAP map-name FORMATTED RULES

Displays all the rules for the specified map.

INLINERULES
Inline Rules Only:
LIST MAP map-name FORMATTED INLINERULES

Displays only the inline rules for the specified map.

FREERULES
Free Rules Only:
LIST MAP map-name FORMATTED FREERULES

Displays only the free rules for the specified map.

AUTORULES
Automatic Rules Only:
LIST MAP map-name FORMATTED AUTORULES

Displays only the automatic rules for the specified map.

List of Objects

When you use asterisk or wildcard notation for the object name, you get a list of all objects that meet the specified selection criteria. On this list, you can then select objects for display, print, etc. by marking them with a function code, or you can enter a Natural system command or a LIST subcommand in the command line.

This section describes the functions, subcommands and function codes that are available in the list of objects which is displayed, for example, after you have issued a LIST * command. The following topics are covered:

Explanation of the Column Headers

The list of objects contains the following columns:

Column Explanation
Cmd In this column, you can enter a code to perform a function on an object in the selection list. See Performing a Function on an Object.
Name Name of object.
Type Type of object.
S/C Indicates whether the object exists as source (S) and/or cataloged object (C).
SM The Natural programming mode that was used when the object was created. S = structured mode, R = reporting mode.
Version Product version of Natural that was used to create or catalog the object.
User ID User ID of the user who created or cataloged the object.
Date, Time Date and time when the object was created or cataloged.

Scrolling the Selection List of Objects

Once a list of objects is displayed, you can scroll it as follows:

New Criteria for the Selection List

When a list of objects is displayed, the fields immediately underneath the column headings show the selection criteria for the current list. You can change the selection criteria by overwriting the values of these fields. For information on the possible values for one of these fields, you enter a question mark (?) in the field.

Information Displayed on the Selection List

If there exists both a source and an object module for an object (as indicated in the column S/C), the information displayed refers to the source, not the object module.

Note:
When the sort function is active the source and the object module may be displayed separately, e.g. when the list is sorted by the object date and the source and the object module have different date values.

Start of instruction setTo display more information on source and cataloged objects

Note:
By default the number of source lines of source objects is not calculated due to performance reasons. If you want the number of source lines of source objects being displayed, you can either enter the subcommand COUNTSOURCE ON or set in the LIST profile (see Defining an Individual List Profile below) the parameter COUNT-SOURCE-LINES to Y.

Items Intensified on the Selection List

If an item is displayed intensified on the left-most list page, this indicates that there is a discrepancy between the object's source and its object module. For information on the discrepancy, you may mark the object with the function code LD to list its directory information. To eliminate the discrepancy, it is usually sufficient to stow the object again (function code ST).

Subcommands for the Selection List

In a list of objects, you can enter a Natural system command or a LIST subcommand in the command line. Valid subcommands are:

Code Function
CODE-PAGE or CP ON Display the code page information for each object. This is the default value.
OFF Do not display the code page information.
SC List only objects containing a scan value (can only be used with long list).
SC OFF Switch off scan mode.
SHORT Display a short list of objects, i.e., display only the object names (can only be used if scan mode is off).
LONG Switch to long list including all fields available.
PRINT Print the list of objects.
EXTENDED Display the list of long names of subroutines/classes; same as LIST EXTENDED *.
ALL fx Enter the function code fx (where fx is a valid function code for a listed object) for all displayed objects.
SORT Invokes the sort window (see Sorting the List of Objects below).
COUNTSOURCE ON Display the number of source lines for source objects.
OFF Do not display the number of source lines for source objects.
MARK-LONG-LINES ON

Mark long lines in the list of a source object with an L in the first two positions.

The default value can be specified in the LIST profile; see Defining an Individual List Profile.

OFF Do not mark long lines in the list of a source object.
DEFINE-DATA ON

A listed data area source is listed in DEFINE DATA format by default (same as LIST dataarea FORMATTED).

The default value can be specified in the LIST profile; see Defining an Individual List Profile.

OFF A listed data area source is listed unformatted.
LISTPROFILE Display the current value of the parameters of the LIST profile (see Defining an Individual List Profile below).
NOCOPT Displays a list of the cataloged objects that are compiled with Natural Optimizer Compiler (NOC), together with the initial NOC options used during CATALOG; same as LIST NOCOPT *, see Displaying NOC Options of Cataloged Objects.
OPTIONS Displays a list of the cataloged objects together with the initial compiler options used during catalog; same as LIST OPTIONS *, see Displaying Compiler Options of Cataloged Objects.
REUSE ON Switch on reuse mode.

The last displayed list is reused after execution of commands entered in the Cmd column, except for the following commands:

E
ED (Edit)
CA (Catalog)
UC (Uncat)
S
ST (Stow)
D
DE (Delete)
RE (Rename)

OFF Switch off reuse mode.

The list is rebuilt after execution of commands entered in the Cmd column.

REFRESH Rebuild the currently displayed list. This subcommand can be used especially when reuse mode is switched on.
+ Scroll one page forward.
- Scroll one page backward.
++ Scroll to the end (bottom) of the object list.
-- Scroll to the beginning (top) of the object list.
? Command line help.

Performing a Function on an Object

To perform a function on an object in the selection list, you simply mark the object with the appropriate function code in the left-hand column (titled Cmd).

You can mark several objects on the selection list with different function codes; the functions will then be performed one after the other.

The following function codes are available (possible abbreviations are underlined).

Code Function
? A window will be displayed which shows all the functions available for the marked object. The window will only list those functions that are actually available for the selected object (for example, if the object is a subroutine, it cannot be run; if the object is only available in source form, it cannot be executed).

From the window you can select the function to be performed on the marked object.

CA Compile the object and store it in object form (equivalent to the system command CATALOG).
DE Delete the object (equivalent to the system command DELETE).
DL Download object from mainframe to personal computer (only available if Natural Connection is installed).
ED Edit the object's source code (equivalent to the system command EDIT).
EX Execute the object (equivalent to the system command EXECUTE).
LC List object's source code converted into the default code page *CODEPAGE, (equivalent to LIST object-name CONVERTED).
LD List directory information (equivalent to LIST DIRECTORY object-name) on the object.
LE List object's source code in expanded form (equivalent to LIST object-name EXPAND *).
LF Display a data area or map formatted (equivalent to LIST object-name FORMATTED).
LI List the object's source code.
LN Display long name of subroutine or class (only possible if a cataloged object exists) or resource.
NO Displays the Natural Optimizer Compiler (NOC) options used during CATALOG (only possible if a catalog object exists).
OP Displays the initial, final and changed Natural compiler options used during CATALOG (only possible if a cataloged object exists).

The initial and changed compiler options can be displayed for objects cataloged with Natural Version 4.2.5 or above only.

PR Print the object's source code.
RE Rename the object (equivalent to the system command RENAME).
RU Run (that is, compile and execute) the object's source code (equivalent to the system command RUN).
ST Stow the object in source and object form (equivalent to the system command STOW).
UC Delete the object module (equivalent to the system command UNCATALOG).
. Exit (from selection list window)

Sorting the List of Objects

The LIST command provides the possibility to sort the list of the displayed objects by several sort criteria.

Note:
To use this function, it is necessary to set the WRKSIZE (Size of Work Buffer Used by Sort Program) in the Natural profile parameter SORT to an appropriate value. The maximum size of the list that can be sorted is limited by the size of this work buffer.

Once the sort has been started, all changes in the Criteria for the Selection List create a sorted list.

Start of instruction setTo switch off the sort mode

The sorted list is built in a Natural text object in library WORKPLAN. The name of the text object is generated by the LIST command. If the LIST profile is activated (see Defining an Individual List Profile below) the name of the text object and the library can be specified in the LIST profile.

Examples of List of Objects Usage

LIST * Lists all objects in the current library.
LIST S * Lists all subroutines in the current library.
LIST SYS* Lists all objects (of any type) whose names begin with SYS.
LIST M SYS* Lists all maps whose names begin with SYS.

LIST NAT*AL Lists all objects whose names begin with NAT and end with AL no matter which and how many other characters are between NAT and AL (this would include the names NATURAL and NATIONAL as well as NATAL).
LIST DOO? Lists all objects with 4-character names beginning with DOO (this would include the names DOOR and DOOM, but not DOO or DOODLE).
LIST M NAT?AL   Lists all maps whose names begin with NAT and end with AL with exactly one character are between NAT and AL (this would include the names NAT1AL and NAT2AL, but not NATAL or NATIONAL).
LIST M *1* Lists all maps whose names contains a 1.
LIST M F> Lists all maps, starting from the first one whose name begins with F.
LIST M MA< Lists all maps, from the first one until the one named MA (if present).

List of Source

The following topics are covered below:

Subcommands for Listed Source

When you have the source code of an object listed, you can enter in the command line one of the following subcommands.

Subcommand Function
+ Scrolls one page forward.
- Scrolls one page backward.
++ Scrolls to the end (bottom) of the source.
BOTTOM
-- Scrolls to the beginning (top) of the source.
TOP
+n Scrolls n lines forward.
-n Scrolls n lines backward.
nnnn Scrolls to line number nnnn.
CONVERTED See CONVERTED in Options.
DBFNR ON Displays the database id (DBID) and file number (FNR) of the source library in the header line of the source code.
DBFNR OFF Displays the header line of the source code without the database id (DBID) and file number (FNR) of the source library. This is the default value.
EXPAND See expand-option.
FIELDS Applies to maps only: displays the field summary; that is, the list of fields in the map.
FIND

Displays only those source lines which contain the specified value.

If you enter only the command FIND itself, a window will be displayed in which you can enter the value to be sought and specify whether the search is to be absolute or not.

If you specify FIND without ABSOLUTE after the command, the value will only be found if it is an isolated word. This is the default.

If you specify ABSOLUTE after the command, the value will also be found if it is part of a larger string of characters.

FIND value
FIND ABSOLUTE value
FORMAT Applies to data areas and maps only: displays formatted data area or map, and other items related to the map.
LAYOUT Applies to maps only: displays the map layout; that is, the map will be displayed as it is displayed to the users at runtime.
NUMBERS ON Displays the source code with line numbers. This is the default value.
NUMBERS OFF Displays the source code without line numbers.
PRINT Prints the listed source.
REF Displays the line numbers of the source-code lines which contain the specified value in a table.

If you enter only the command REF itself, a window will be displayed in which you can enter the value to be sought for and specify whether the search is to be absolute or not.

If you specify REF without ABSOLUTE after the command, the value will only be found if it is an isolated word. This is the default.

If you specify ABSOLUTE after the command, the value will also be found if it is part of a larger string of characters.

REF value
REF ABSOLUTE value
RULES Applies to maps only: displays the processing rules used by the map (the rules are displayed in order of fields to which they are assigned, and per field in order of rank).
SCAN Displays all lines intensified which contain the specified value. The source will be scrolled to the first line that contains the value.

If you enter only the command SCAN itself, a window will be displayed in which you can enter the value to be sought for and specify whether the search is to be absolute or not.

If you specify SCAN without ABSOLUTE after the command, the value will only be found if it is an isolated word. This is the default.

If you specify ABSOLUTE after the command, the value will also be found if it is part of a larger string of characters.

SCAN value
SCAN ABSOLUTE value
SCAN= or SC= Scans for the next occurrence of the last SCAN value (or press PF5).
SETTINGS Applies to maps only: displays the map settings of the map.
ZOOM [expand-type...10] object-name Specifying a single object-name with the ZOOM command has the same effect as marking the name in the listed source with the cursor (see the section Cursor-Sensitive Object Selection): the selected object will be displayed in a window.

If you use asterisk/wildcard notation for the object-name or the object-name-range, all selected objects will be displayed in a window in the sequence in which they are referenced in the listed source.

The specification of an expand-type is the same as for the expand-option.

For an object displayed within a window invoked by ZOOM, the same subcommands (except PRINT, EXPAND and ZOOM) are available as for the normal listed source. Moreover, if you have used asterisk or wildcard notation and several objects are displayed, you can use the commands NEXT and PREV (or PF4 and PF5) to move from one object in the window to the next one or previous one respectively.

ZOOM [expand-type...10] object-name-range
. Exit.

Note:
By default, the database id (DBID) and file number (FNR) of the source library are not displayed in the header line of the listed source. If you want the DBID and FNR of the source library to be displayed, you can either enter the subcommand DBFNR ON or, in the LIST profile, set the parameter SOURCE-LIST-WITH-DBID-FNR to "Y" (see Defining an Individual List Profile below).

Subcommand FORMAT

This subcommand only applies to stowed data areas (where time stamp of source object and cataloged object are identical) and maps.

For data areas, this subcommand corresponds to the option FORMATTED.

In the List Profile, you can specify how data areas are listed by default:

In the List of Objects, you can use the subcommand DEFINE-DATA ON/OFF to set the default for the time the LIST command is being executed.

If data areas are listed formatted by default and if it is not possible to convert the data area source code into DEFINE DATA format, a corresponding message is displayed and the data area is listed unformatted.

When you enter the subcommand FORMAT for a map, a window will be displayed in which you can select one or more additional items related to the map to be displayed:

The items you select are displayed one after the other in the order in which they appear in the selection window.

In FORMAT mode, the same subcommands for scrolling - except B - and the subcommands FIELDS, LAYOUT, PRINT, RULES and SETTINGS are available as for a normal listed source (see above). Additional subcommands are available as described below for each item.

Additional Subcommands for Map Layout

S>n Shift map layout n columns to the right.
S<n Shift map layout n columns to the left.

To have the extended field editing information for an individual field displayed, mark the field name on the field summary list with the cursor and press ENTER.

To have the processing rules of a field displayed, you can also enter an R in the command line and then mark the field name on the field summary list with the cursor and press ENTER.

Cursor-Sensitive Object Selection

Within a source that is being listed, you can mark with the cursor the name of an object referenced within that source, and the source of the selected object will be listed in a window.

For the source displayed within the window, the same subcommands - except PRINT, EXPAND and ZOOM - are available as for the "normal" listed source.

Defining an Individual List Profile

You can define an individual profile for the LIST command. For this purpose, Natural provides the text object LISTPROF in the library SYSLIB.

In LISTPROF, you can enter general or user-specific profiles with corresponding defaults, such as COUNT-SOURCE-LINES. These defaults are used when you start the LIST command.

Start of instruction set To activate the values defined in LISTPROF

  1. Copy the text object LISTPR-S from library SYSLIB to any library.

  2. Add the changes.

  3. Save the text object LISTPR-S under the name LISTPROF.

  4. Copy the text object LISTPROF to library SYSLIB.

  5. Invoke the LIST command.

For a detailed description, see text object LISTPR-S in library SYSLIB.
