IBM OS WRITER TAPE ORGANIZATION
12-2 XEROX LASER PRINTING SYSTEMS TAPE FORMATS MANUAL
Job Descriptor Library (JDL) specification
The Xerox system looks for banner page delineation of OS Writer
stacked reports whenever the HOST=OSWTR left/right parts are
specified in the VOLUME statement. Additionally,
“LABEL=STANDARD” should be specified.
While the HOST and LABEL left/right parts are mandatory, the
VOLUME left/right parts “OSCHN”, “OSTLP”, and “OSHDP” may be
specified at the PDL programmer's discretion, according to the
criteria specified in table 12-1.
The full selection of PDL commands may be used in selecting the OS
Writer option. Generally, however, only the LINE and OUTPUT
commands are needed (in addition to the VOLUME command) due
to the override of BLOCK and RECORD values by the HDR2 label
information contained on these tapes.
Sample report creation under an OS Writer
An installation's management and systems analyst usually determine
how to apply the OS Writer feature of the Xerox system to the
installation's processing scheme. An example of OS Writer report
generation has been included in this section to assist those
unfamiliar with OS and OS/VS Writers. The description is meant to
be illustrative rather than exhaustive, as each OS installation varies
widely in actual application.
