Introduction

An important part of an MVS application is the JCL jobstream that controls its execution. MSS provides facilities to support the use of batch JCL jobstreams on the PC or UNIX workstation. Within Enterprise Developer, you can:

• Create new jobstreams
• Scan the jobstreams for syntax errors and dependencies
• Submit the jobstreams for running in an enterprise server and view the spool output files

A major objective of the JCL support is to keep the operations in MSS as similar as possible to those done on the mainframe. Thus in MSS, you can:

• Use mainframe data set names in the jobstream, even though the data is held in a file on the PC or UNIX workstation
• Process jobstreams as if they were being run on the mainframe

• View and process the SYSOUT listing and any other printed output produced by the jobstream

• Use the functions of the many mainframe batch utilities

Before you start to use the JCL support in MSS, you need to understand more about the following topics:

• JCL jobstreams
• Data sets
• Application programs
