This must be done with an RHDCSGEN batch job step (System Generation in batch).
Use the RHDCSGEN batch job step in JOB17 of the configuration process as a sample.
Replace the SYSIPT with this:
//SYSIPT DD *
SIGNON DICTIONARY SYSTEM.
COPY PROGRAMS FROM SYSTEM 99 TO nnn.
COPY TASKS FROM SYSTEM 99 TO nnn.
Change the nnn to the system number of your CA-IDMS CV. This is what you set GJDCSYS to in VARBLIST, and is also the number displayed after the V in the ENTER NEXT TASK CODE: prompt.
Run the job step and then cycle the CV to bring in the new PROGRAMs and TASKs.
