Hi,

we are trying the following:

when the user starts a runtime we want the initial program A to call a little program B (as a thread) that runs independently as long as the runtime is running.

Even if for example program A calls program C with CALL PROGRAM.

 

Is this possible ? How would you achive this ?

The thread was our first idea. If you come up with something other than thread we are open for your solution.

Hello,
indeed, the best way of doing this is using a thread.
You can find a sample in the Thread Demo sample (Source: custrpt.cbl)

Thanks for your answer.

Are you sure the thread will continue after the calling program A has called another "main program" via CALL PROGRAM ?

Or do these rules apply:

The CALL PROGRAM verb is similar to the CHAIN verb. It causes the current run unit to terminate and initiates a new run unit.
When the called program exits, its thread is terminated.

Hi,
when you use CALL THREAD "PROGRAM-B" program-b keeps running until it is terminated by the user or when the processing has finished, or until the main-program is terminated. We make sure of that by using STOP THREAD in the main-program. Program-b should have GOBACK instead of STOP RUN in it's closing routine.
Be aware that you not calling the main-program from program-b, because you will create a loop which will give unpredictable results.

For clarification 'CALL PROGRAM <program name>' and 'CALL <program name>' are two different operations. You can NOT use CALL PROGRAM for the scenario you are describing. Thread usage is only available with the CALL operation as described by ruudh.

Thanks DougP, that was exactly my state of knowledge ... unfortunately.

So we have to look for another solution to our problem.
