Belongs to Function Group: Creation of Output Reports
The DEFINE PRINTER
statement is used to assign a symbolic
name to a report number and to control the allocation of a report to a logical
destination. This provides you with additional flexibility when creating output
for various logical print queues.
When this statement is executed and the specified printer is already
open, the statement will implicitly cause that printer to be closed. To
explicitly close a printer, however, you should use the
CLOSE PRINTER
statement.
For further information on the DEFINE PRINTER
statement,
see Unicode
and Code Page Support in the Natural Programming Language,
section
Statements.

This section covers the following topics:
For a printer number that is defined with access method
AM=STD
,
you can use operand1
to specify a
logical or a physical data set name to be assigned to that printer number.
operand1
can be 1 to 253
characters long and can be one of the following:
a logical data set name (DD name, 1 to 8 characters);
a physical data set name of a cataloged data set (1 to 44 characters), or a physical data set member name (1 to 44 characters for the data set name, plus 1 to 8 characters in parentheses for the member name);
a path name and member name of an HFS file (1 to 253 characters) in an MVS UNIX Services environment;
a JES spool file class;
NULLFILE
(to indicate a dummy data set).
For example:
DEFINE PRINTER (21) OUTPUT 'SYSPRINT'
The specified data set with DD-name SYSPRINT
must have
been allocated before the DEFINE PRINTER
statement is executed.
For further information, see
Allocation
and De-Allocation of Data Sets.
The allocation can be done via JCL, CLIST (TSO) or dynamic allocation
(SVC 99). For dynamic allocation you can use the application programming
interface USR2021N
in library SYSEXT
.
The data set name specified in the DEFINE PRINTER
statement overrides the name specified with the keyword subparameter
DEST
of
profile parameter PRINT
.
Optionally, the data set name may be prefixed by DDN=
to
indicate that it is a DD-name and to avoid name conflicts with additional
reports. For example:
DEFINE PRINTER (22) OUTPUT 'DDN=SOURCE'
For example:
DEFINE PRINTER (23) OUTPUT 'TEST.PRINT.FILE'
The specified data set must exist in cataloged form. When the
DEFINE PRINTER
statement is executed, the data set is allocated
dynamically by SVC 99 with the current DD-name and JCL option
DISP=SHR
. For further information, see
Allocation
and De-Allocation of Data Sets.
If the data set name is 8 characters or shorter and does not contain a
period (.), it might be misinterpreted as a DD-name. To avoid this, prefix the
name with DSN=
. For example:
DEFINE PRINTER (22) OUTPUT 'DSN=PRINTXYZ'
If the data set is a PDS member, you specify the PDS member name (1 to 8 characters) in parentheses after the data set name (1 to 44 characters). For example:
DEFINE PRINTER (4) OUTPUT 'TEST.PRINT.PDS(TEST1)'
If the specified member does not exist, a new member of that name will be created.
For example:
DEFINE PRINTER (14) OUTPUT '/u/nat/rec/test.txt'
The specified path name must exist. When the DEFINE
PRINTER
statement is executed, the HFS file is allocated dynamically. If
the specified member does not exist, a new member of that name will be
created.
For the dynamic allocation of the data set, the following z/OS path options are used:
PATHOPTS=(OCREAT,OTRUNC,ORDWR) PATHMODE=(SIRUSR,SIWUSR,SIRGRP,SIWGRP) FILEDATA=TEXT
When an HFS file is closed, it is automatically de-allocated by z/OS
(regardless of the setting of keyword subparameter
FREE
of
profile parameter PRINT
).
To create a JES spool data set, you specify
SYSOUT=x
(where
x is the desired spool file class). For the default
spool file class, you specify SYSOUT=*
.
Examples:
DEFINE PRINTER (10) OUTPUT 'SYSOUT=A' DEFINE PRINTER (12) OUTPUT 'SYSOUT=*'
To specify additional parameters for the dynamic allocation, use
application programming interface USR2021N
in library
SYSEXT
instead of the DEFINE PRINTER
statement.
To allocate a dummy data set, you specify NULLFILE
as
operand1
:
DEFINE PRINTER (n) OUTPUT 'NULLFILE
This corresponds to the JCL definition:
// DD-name DD DUMMY
When the DEFINE PRINTER
statement is executed and a
physical data set name, HFS file, spool file class or dummy data set has been
specified, the corresponding data set is allocated dynamically. If the logical
print file is already open, it will be closed automatically, except when the
keyword subparameter CLOSE=FIN
(Time of
Closure) of profile parameter PRINT
has been
specified, in which case an error will be issued. Moreover, an existing data
set allocated with the same current DD-name is automatically de-allocated
before the new data set is allocated.
To avoid unnecessary overhead by unsuccessful premature opening of
print files not yet allocated at the start of the program, print files should
be defined with keyword subparameter
OPEN=ACC
(open at first access) of profile parameter PRINT
.
In the case of an HFS file, or a print file defined with the keyword
subparameter FREE=ON
of profile
parameter PRINT
, the print
file is automatically de-allocated as soon as it has been closed.
As an alternative for the dynamic allocation and de-allocation of data
sets, the application programming interface USR2021N
in library
SYSEXT
is provided. This API also allows you to specify additional
parameters for dynamic allocation.
In server environments, errors may occur if multiple Natural sessions
attempt to allocate or open a data set with the same DD-name. To avoid this,
you either specify the print file with keyword subparameter
DEST=*
of
profile parameter PRINT
, or you
specify OUTPUT '*'
in the DEFINE PRINTER
statement;
Natural then generates a unique DD-name at the physical data set allocation
when the first DEFINE PRINTER
statement for that print file is
executed.
All print files whose DD-names begin with CM
are shared by
all sessions in a server environment. A shared print file is opened by the
first session, and is physically closed when the server is terminated. For
further information, see the section
Natural as a
Server in the Operations
documentation.
For a printer number that is defined with the access method
AM=STD
,
operand1
can be:
a logical data set name (DD-name, 1 to 7 characters);
NULLFILE
(to indicate a dummy data set).
Example:
DEFINE PRINTER (2) OUTPUT 'SYSOUT1'
The specified data set SYSOUT1
must have been defined in
the JCL or in the z/VSE standard or partition labels.
The data set name specified in the DEFINE PRINTER
statement overrides the name specified with keyword subparameter
DEST
of
the PRINT
profile
parameter.
Optionally, the data set name may be prefixed by DDN=
to
indicate that it is a DD-name. For example:
DEFINE PRINTER (5) OUTPUT 'DDN=MYPRINT'
To allocate a dummy data set, you specify NULLFILE
as
operand1
:
DEFINE PRINTER (n) OUTPUT 'NULLFILE
For a printer number that is defined with the access method
AM=STD
,
you can use operand1
to specify a file name, link name or system file that is allocated to this
printer number.
In this case, operand1
can have
a length of from 1 to 253 characters and one of the following meanings:
*DUMMY
The following rules apply:
File name and link name can be specified as positional parameters or
keyword parameters. The corresponding keywords are FILE=
and
LINK=
. Mixing positional and keyword parameters is allowed but not
recommended.
A string with a length of 1 to 8 characters without commas is interpreted as a link name. This notation is compatible with earlier versions of Natural. Example:
DEFINE PRINTER (1) OUTPUT 'P01'
The corresponding definition with a keyword subparameter is:
DEFINE PRINTER (1) OUTPUT 'LINK=P01'
A string of 9 to 54 characters without commas is interpreted as a file name. Example:
DEFINE PRINTER (2) OUTPUT 'NATURALvr.TEST.PRINTER02'
where vr represents the relevant product version.
The corresponding definition with a keyword subparameter is:
DEFINE PRINTER (2) OUTPUT 'FILE=NATURALvr.TEST.PRINTER02
The following input is interpreted without considering the length and therefore forms exceptions to Rules 2 and 3:
keyword input: LINK=
, FILE=
*DUMMY
NULLFILE
(equivalent to *DUMMY
)
*
*,*
SYSOUT
SYSLST
or
SYSLST(nn)
Example: DEFINE PRINTER (7) OUTPUT 'FILE=Y'
is a valid
file allocation and not a link name, although the string of characters contains
fewer than 9 characters.
Generic file names are formed as follows:
pnn.userid.tsn.date.time.number
where
nn
|
is a report number |
userid
|
is a Natural user-ID, 8 characters |
tsn
|
is the BS2000 TSN of the current task, 4 digits |
date
|
is DDMMYYYY |
time
|
is HHIISS |
number
|
is a sequential number, 5 digits |
Generic link names are formed as follows:
NPFnnnnn
where nnnnn
is a 5-digit
number that is increased by one after every generation of a dynamic link
name.
Changing the file allocation for a printer number causes an implicit
CLOSE
of the print file allocated so far.
You are strongly recommended, in all cases except when you only specify
a link name (for example: P01
), to work with keyword parameters.
This avoids conflicts of names with additional reports and is essential for
file names with fewer than 9 characters.
Examples:
DEFINE PRINTER (1) OUTPUT 'LINK=SOURCE' DEFINE PRINTER (1) OUTPUT 'FILE=SOURCE' DEFINE PRINTER (1) OUTPUT 'SOURCE'
Example:
DEFINE PRINTER (1) OUTPUT 'LINKP01'
means the same as
DEFINE PRINTER (1) OUTPUT 'LINK=LINKP01'
A file with the link LINKP01
must exist at runtime. This
can be created either by using JCL before starting Natural or by dynamic
allocation from the current application. For dynamic allocation, the
application programming interface USR2029
in the library can be
used. If, before execution, the link was active as a destination to another
file, for example P01
, this will be released or retained depending
on the value of the keyword subparameter
FREE
of profile parameter PRINT
(possible
values are ON
and OFF
). Release is done via an
explicit RELEASE
call to the BS2000 command processor.
Example:
DEFINE PRINTER (2) OUTPUT 'NATURALvr.TEST.PRINTER02'
where vr represents the relevant product version.
means the same as
DEFINE PRINTER (2) OUTPUT 'FILE=NATURALvr.TEST.PRINTER02'
The file specified in operand1
is set up using a FILE
macro call and inherits the link name that
was valid for the corresponding print file before execution of the DEFINE
PRINTER
statement.
Example:
DEFINE PRINTER (21) OUTPUT '*'
means the same as
DEFINE PRINTER (21) OUTPUT 'FILE=*'
A file with a name created according to Rule 4 is set up using a
FILE
macro call and inherits the link name that was valid for the
corresponding print file before execution of the DEFINE PRINTER
statement.
DEFINE PRINTER (22) OUTPUT 'FILE=*,LINK=GENFLK22'
A file with a name created according to Rule 4 is set up with the
specified link name using a FILE
macro call.
Example:
DEFINE PRINTER (11) OUTPUT 'NATURALvr.TEST.PRINTER11,LNKP11'
where vr represents the relevant product version.
means the same as
DEFINE PRINTER (11) OUTPUT 'FILE=NATURALvr.TEST.PRINTER11,LINK=LNKP11'
which means the same as
DEFINE PRINTER (11) OUTPUT 'FILE=NATURALvr.TEST.PRINTER11,LNKP11'
The file specified in operand1
is set up with the specified link name using a FILE
macro call and allocated to the corresponding printer number.
Example:
DEFINE PRINTER (27) OUTPUT '*,*'
means the same as
DEFINE PRINTER (27) OUTPUT 'FILE=*,LINK=*'
A file with a file name and link name created according to Rule 4 and
Rule 5 is set up using a FILE
macro call and allocated to the
specified printer number (27).
Note:
When file name and link name are specified, the previous link name
is not released, regardless of the value of keyword subparameter
FREE
of
profile parameter PRINT
.
Example:
DEFINE PRINTER (14) OUTPUT 'SYSOUT'
Report 14 is written to SYSOUT
.
Under TIAM: SYSOUT
is by default output on the
screen.
Example:
DEFINE PRINTER (15) OUTPUT 'SYSLST'
Report 15 is written to the system file SYSLST
.
Example:
DEFINE PRINTER (16) OUTPUT 'SYSLST16'
Report 16 is written to the system file SYSLST16
.
Examples:
DEFINE PRINTER (11) OUTPUT 'SYSLST=LST.PRINTER11'
The system file SYSLST is allocated to the file
LST.PRINTER11
; Report 11 is written to the system file
SYSLST
.
DEFINE PRINTER (13) OUTPUT 'SYSLST13=LST.PRINTER13'
The system file SYSLST13
is allocated to the file
LST.PRINTER13
; Report 13 is written to the system file
SYSLST13
.
DEFINE PRINTER (19) OUTPUT 'SYSLST19=*'
The system file SYSLST19
is allocated to a file with a
name generated according to Rule 4; Report 19 is written to the system file
SYSLST19
.
For a printer number defined with the access method
AM=CICS
, operand1
can be a transient data or temporary storage queue name (1 to 8 characters),
depending on keyword subparameter
TYPE
of profile parameter PRINT
for the
printer. For TYPE=TD
(transient data), only the first 4 characters
of operand1
are honored and the
transient data destination must be predefined to CICS.
For further information, see also Natural Print and Work Files under CICS (in the TP Monitor Interfaces documentation).
With AM=COMP
, a valid
printer number (TID) or a logical printer name can be assigned. For
example:
DEFINE PRINTER (1) OUTPUT '11' DEFINE PRINTER (2) OUTPUT 'P102'
With AM=SMARTS
, any
printer name can be assigned. For example:
DEFINE PRINTER (14) OUTPUT '/nat/path/printer' DEFINE PRINTER (14) OUTPUT '/nat/path/printer/file/' DEFINE PRINTER (14) OUTPUT 'printer'
It depends on the MOUNT_FS
parameter of SMARTS
whether the file is located on a SMARTS portable file system or on the native
file system. The first element of the path (/nat/)
determines the
target file system.
If the string is terminated with a slash (/), the last element is taken
as the name of the print file. Otherwise, the name of the file is generated
from the UserID
and a sequence number. If the string does not
start with a slash, the path of the file is taken from the environment variable
$NAT_PRINT_ROOT
.
The specified path name must exist. When the DEFINE PRINTER
statement is executed, the file is allocated dynamically. If the specified
member does not exist, a new member of that name will be created.
For Natural Advanced Facilities users, the name of any predefined
logical printer profile can be specified. This logical printer profile needs
not belong to the currently active user profile. It may be any logical printer
profile defined on the NATSPOOL
file. It will be active only for
the duration of the Natural program which contains the DEFINE
PRINTER
statement. For further information, see the
Natural
Advanced Facilities documentation.
Additional reports and remote print destinations can be assigned by default with the following names:
Report | Function |
---|---|
BROADCST
|
Output message line to a TP monitor terminal. Same function as
MESSAGE (see below), except that under Com-plete, the message is
not sent to the desired terminal until no transactions are active on that
terminal.
|
CCONTROL
|
CCONTROL is the name of a special printer control
table associated to the printer n-1; it must not be
modified. For further information, refer to
Printer-Advance Control Characters
(in the Operations documentation).
|
CONNECT
|
Output into a Con-nect folder.
Note for Natural installation: The |
DUMMY

Output into the NSPF incore database. |
INFOLINE
|
Output to the Natural infoline. For details on the infoline, see
the Natural terminal command %X .
|
MESSAGE
|
Output message line to a TP monitor terminal. The first 8 bytes
of a message must contain the target terminal ID. TSO
require the user ID
instead of the terminal ID. An example program MSGSW is supplied
in the library SYSEXTP .
