I was a bit confused it I can call a batch pgm from a CICS module and if i can call a CICS module from a batch module ?

Asuming that the CICS module have really CICS sentences and the BATCH program process sequential files or reports... the answer, AFAIK, is NO.

toharmeet,

Don't know what your exact requirements are. But look up the following topics. Maybe they will help.

1. Calling CICS programs from non-CICS env - Search for EXCI or CICS External Call Interface. I remember, IBM also has a guide specifically for external call interfaces.

2. Submitting bacth jobs from CICS (Not calling batch programs - where will they run???) - You can use TDQs allocated to INTRDR for submitting batch jobs to JES from CICS transactions.

Search for the above topics in Google or IBM book Manager. You will get a lot of info. HTH...

Regards,
Manas

As long as your batch (non CICS - no CICS API's invoked) modules do NOT have FD's you can CALL them from CICS modules all day long... Batch module should not attempt to pass (USING) data areas larger than a 4k page to another batch module.

Helped write a core booking system which was all batch COBOL/DB2 - some 800 modules, that replaced the old CICS update process. The CICS front end CALLed the batch primary module and depending upon the booking process, anywhere from 19 to 130 modules would be CALLed to process a transaction.

I forgot to mention in the previous post - all dynamic CALLs, not static.....

1. You can call a batch program from a CICS program if the batch program has no file access or other routine that would have to be handled by CICS.

2. You can call a CICS program from a batch program like below.

dbzTHEdinosauer,

Thanks for the info. Never really did that before. Was good information. Always thought that any program running on the CICS address space has to have a PPT entry defined. Will try that out if I get a chance. Thank you.

Manas
