Hi all,

I need the syntax of Detach command in CICS. Also It would be of great help if anyone can explain its use.

Thanks in advance...

There is a link to manuals at the top of the page. Click on it, find the CICS manuals, and read them -- if what you read is not clear, please post again.

A DETACH command is not a CICS command/API at all.

It is an MVS (z/OS) Macro, primarily used together with a previous MVS ATTACH Macro.

Using MVS (z/OS) Macro's in CICS should be limited and infrequent, because many expand into SVC's (Supervisor Call), which stop the region until the SVC is complete and you may get a visit from your Performance and/or System personnel.

Hi Bill,

Thanks for the reply.

But I am still confused as I got the design for the program from onsite and the designer has clearly mentioned that "Each time <pgm name> is triggered, it should perform an EXEC CICS DETACH before it starts processing."

This gives a feeling as if DETACH is a CICS command!!!

Since you don't seem to believe the manual that IBM wrote which gives all of the CICS commands, Google "exec cics detach" with the quotes and see how many hits show up. The total is ... ZERO. Should you believe IBM and Google, or should you believe the comments a programmer at your shop made? Your choice.

to the cics manual where the "EXEC CICS DETACH" is described

Hello,

But you still have a "designer" who wants "something" to happen. . .

Suggest this needs clarification . . .

this makes no sense, even if there was a DETACH command, why
would you want to DETACH when you just got started ?
