This Natural profile parameter can be used to separate program output from Natural system output, which may be useful particularly in batch mode.
| Possible settings | 0 - 31 |
Valid printer number. |
|---|---|---|
| Default setting | 0 |
|
| Dynamic specification | yes | |
| Specification within session | no | |
| Application Programming Interface | USR6002N |
See SYSEXT - Natural Application Programming Interfaces in the Utilities documentation. |
This applies to program output for Report 0, as produced by
DISPLAY,
PRINT,
WRITE or
INPUT statements
(except INPUT statements which contain non-protected input fields
(field attribute specification AD=A) or modifiable input
fields (AD=M)).
If the MAINPR parameter is specified,
program output for Report 0, which would normally be output on the printer
assigned to Report 0, is output on the printer specified with
MAINPR instead; while system output (NEXT
prompt, DATA prompt, etc.) is always output on the primary output
device (Report 0); the MAINPR setting must be a valid
printer number (0 - 31).
A logical printer corresponding to the report number specified
must be defined to Natural. A printer is defined with the profile parameter
PRINT, with the
macro NTPRINT
or automatically by JCL (in batch mode or under TSO).
The MAINPR parameter does not apply to
output from system programs in the Natural system library SYSLIB,
which is always output on the primary output device (Report 0).
