EXCI on CICS Map program

Suceender Kumar · Posted: Fri May 24, 2013 5:04 pm

Hi,

Can you please explain in high level on how EXCI execute on a CICS program that is having a MAP. For example in new customer addition screen, if we invoke this screen transaction through non CICS Application program or through a COBOL batch program to make an entry how the SEND and RECEIVE map command will react. Whether it will have any special control on SEND and RECEIVE command when it is triggered through EXCI? Or EXCI executing CICS program should not have any MAP in it?

I am new to this EXCI. Please excuse if it doesn’t make sense.

If you click on the IBM Manuals link at the top of the page, find the CICS TS/zOS Application Programming Guide manual, and start looking at EXCI, you will (eventually) find section 3.11.4.3.8 and Table 23, which provides you a list of the CICS API commands that cannot be used with EXCI (also called distributed program link or DPL) programs. All forms of RECEIVE and SEND MAP are explicitly NOT allowed in an EXCI program. So the answer to your questions is that since the EXCI interface won't allow use of any map commands, the issue does not exist.

From my personal experince what you could do is have input and output file and read from and write to them pretending it to be like COMMAREA so you know the values which is sent and received.
