Attention: If you are running
Enterprise Developer version 7.0 or earlier, you must convert your JCL spool files to the format used for versions 7.0 patch update 1 and later.
See
mfsplcnv Spool Conversion Utility for details.

MSS emulates the spooler functions of the mainframe's job entry system. You can select emulation of VSE, JES2 or JES3.
MSS creates a spool file for each of the following:
- Each job that is run. The spool file lists the jobstream and shows the results of each job step.
- Each output data set that is directed to SYSOUT. The spool file shows the contents of the data set.
In MSS, a JCL jobstream can have only one job but the job can contain multiple job steps. You use an EXEC statement to specify
the program to be executed by a job step. You can do this either directly:
EXEC PGM=program-name
or indirectly, using a cataloged procedure:
EXEC PROC=procedure-name ---------> EXEC PGM=program-name.
Although the Catalog
page does not include spool files, they are assigned data set names.
If the data set name is not specified, the MVS name has the form:
Yyyyy.Smmdd.Shhmmss.Jjjjjjjj.Dnnnnn.ddname
If the data set is temporary, the MVS name has the form:
Yyyyy.Smmdd.Shhmmss.Jjjjjjjj.ANDAND.tempname
where:
- yyyy is the year
- mmdd is the month and day
- hhmmss is the time
- jjjjjjj is the job number
- nnnnn is a number assigned by MSS. It indicates the order in which the data set was created by the job (00000 for the JOBLOG(JCL)
file that shows the results of scanning or running a jobstream).
- ddname is the DD name (for SYSOUT files only)
- tempname is the temporary name, specified as &&tempname in the DD statement.
