Hello,

I have a query regarding autocommit in IMS.
Will a commit be issued when a program logically ends. For example, program A calls B. Program B updates an IMS database. When the control comes back from B to A will an autocommit be issued?

Hello and welcome to the forum,

Returning from a call is not a logical end of a program. As far as the system is concerned it is all one process - just a different bit of code executing.

Hi,

Thanks for your reply.

Just 1 more query. When the call is returned, isnt it a logical end to program B, because the control is out of B now?

Hello,

No.

What has happened is quite similar to a PERFORM.

The process branched to some code and then came back. B never "had control".
