Hi,

I have 3 programs PGM1 calls PGM2, PGM2 inturn calls PGM3.

How will this be treated by CICS, when there are updates in all 3 pgms.

1) If we use XCTL (PGM1 XCTL PGM2, PGM2 XCTL PGM3) ? does all the pgms belong to same task ??

2) If we use LINK or CALL in place of XCTL above, does they belong to same task ?

Need to know the difference because, in case of SYNCPOINT / ROLLBACK the behaviour depends on whether it belongs to same task or not ?

Thanks.

Hema manyam,

If you are using XCTL/LINK in your program to call other programs, all program execution will be treated as a single task only. If you really want to go for a separate task for each program, change your program in such a way to use START command in CICS instead of XCTL/LINK. Using START command, you can start a new transaction(program) which will be separately a new task.
