File Level

The following standards apply to coding printer file DDS at a file level:

If a report will normally be printed on a special forms type, include a ‘line up’ triangle to help the operator.
If a report is produced at all by a program, it must have headings—even if there is no data (print ‘** NO DATA **‘ in such a case).
Printed reports should end by printing ‘** END OF REPORT **’ as the last line in the report. This enables the user to be confident of having all the pages of a report.

The following are the default printer file names:

QSYSPRT	System prints, and system print key.
QPRINT	Program described reports.
QPJOBLOG	Job logs.
YPRTKEY$	Print key: a different file is used from QSYSPRT, so that print key output (which is usually required locally) can easily be redirected to a local printer.

Note: Printer files should normally be created with scheduling defaults of SCHEDULE(*FILEEND) and HOLD(*YES). This means that they must be explicitly released on demand.
