Specify the Parameter Source

All initialization parameters are provided using the PARMLIB DD statement. This DD statement can point to a sequential data set, SYSIN data set, or partitioned data set (PDS). If PARMLIB is specified as a sequential or SYSIN data set, only that data set is processed (multiple data sets can be concatenated in the JCL).

If PARMLIB specifies a PDS (and no member name is included in the DD entry), processing proceeds as follows:

• The EXEC card PARM field is examined and the first blank-delimited word is assumed to be the initial member name for PARMLIB processing.
• If a member name is not specified in the PARM field, or if the first word is *, the default member is SRVPARM.
• Whenever an INCLUDE parameter is encountered, processing of the current member is suspended and processing of the newly specified member is begun.
• At end-of-file, processing resumes with the suspended member and the record following the INCLUDE. When the end of the file is encountered in the initial member, PARMLIB processing completes.
• Although a member can be included more than once, an INCLUDE statement cannot specify a currently suspended member (recursion).
