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.[1]

MSS emulates the spooler functions of the mainframe's job entry system. You can select emulation of VSE, JES2 or JES3.

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:

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
