Fn", rL SOURCE CMSLlB SYSTERM SYSUT LISTING TEXT Notes 4 DMSERS is called to erase the old TEXT, LISTING, and SYSUT files
associated with the new input file. DMSSMN (GETMAIN) is called to
obtain enough storage to contain
the SYSUT1 work file.
When disk space is obtained for the
required assembler files and for the
files CMS needs (SYSTERM and CMSLlBl. FILEDEF commands are
issued to convert all the files to CMS format. The assembler is then called
and begins processing.
5 If possible, all SYSUTt records are
kept in virtual storage during an
assembly. However, when virtual
storage is exhausted, records are
written to disk. If the records must be written to disk,
they are formatted to fit DASD requirements and moved to disk a
record at a time.
6 All SYSUT files used during the
assembly are erased via a call to DMSERS. DMSFNSA is called to
close all files and DMSFLD is called
to clear all FILEDEFs not defined
with the PERM option. COMPSWT in OSSFLAGS is turned off to indicate
that the assembler is no longer
processing, the auxiliary directory
list is released, and control returns to , ...... > DMSERS DMSFNSA Module 6 Process assembler output and

used as the default FI LEDEF filename.

the filename, the message DMSLKD070E INVALID PARAMETER

is issued. Flags are set to reflect the
following options - PRINT, NOPRINT, DISK, SIZE, NAME, TERM, NDTERM'I and LISE. If they are specified,
membername and libraryname are
moved into the FILEDEF commands. If NAME or LISE is specified without
a corresponding name, the message DMSLKDOO5E NO 'option' SPECIFIED is issued.
3 The STATE macro is issued to check
that the input file exists. If it does not,
the message DMSLKDOO2E FI LE 'fn ft' NOT FOUND is issued. If the input file does not
contain fixed 80-character records,
the message DMSLKDOO7E FILE 'fn ft' IS NOT FIXED, 80 CHAR. RECORDS is issued. 4 The CMS file definition function is
called to create a file control block

The CMS erase function is called to
