Specifying the MVS Source File Location
You can specify the location of the source file as a DSN DD card in the compile job instead of specifying a UNIX System Services (USS) directory in the classpath where the source file is located. This eliminates the need to transfer existing sources from a dataset to a USS directory.
However, if the COBOL sources are to be stored in the USS, this option must be switched off manually:
# USING MVS PATHS IN COMPILE JCL TO SPECIFY THE SOURCE FILE
# - 1: SPECIFY SOURCE MEMBER IN 'JPZSRC' DD CARD
# - 0: SOURCE FILE IS TAKEN FROM 'SOURCE' DIRECTORY
