Central Version JCL

The following JCL is used to execute the system generation compiler under the central version.

RHDCSGEN

// EXEC PROC=IDMSLBLS
// UPSI    b                         if specified in the IDMSOPTI module
// EXEC    RHDCSGEN

Input source system generation statements here

/*

You can define a SYSCTL file in the JCL to override IDMSOPTI specifications for central version operations. The SYSCTL file definition is included in the IDMSLBLS procedure (shown next).

Local Mode JCL

To execute the system generation compiler in local mode:

• Remove the UPSI specification.
• Insert the following statement before the EXEC statement:

  // TLBL    sys009,'idms.tapejrnl',,nnnnnn,,f
  // ASSGN   sys009,TAPE,vol=nnnnnn
  

Store Source Statements in a Source Library

You can store some or all of the source statements to be submitted to the system generation compiler as a member in a source statement library. To copy the library member into the job stream, you use the =COPY facility, which is implemented through the =COPY IDMS statement.

The =COPY IDMS statement identifies the source statement library member. You code the statement in the JCL along with other source statements (if any) to be submitted to the compiler. You can code multiple =COPY IDMS statements to identify multiple source statement library members that contain different system generation statements.

=COPY IDMS statements and source system generation statements can be intermixed in the JCL. The source statements are submitted to the compiler in the order in which they occur, whether they are coded directly in the JCL or copied in through the =COPY facility.
