Wish you all a very happy New Year..

How to control infinite loop problem in REXX.
Suppose if we are using some JCL code we can put TIME parameter in the jobcard itself. Is there any other way to control timing in REXX EXEC?

you could do well by taking care while coding the program ! ... hmmm ... if you want to control the time of execution then press attention key while the rexx program is executing and enter 'hi' afterwards. that will terminate it.

Bond,
Your solution would apply for a foreground execution. HI, meaning, Halt Interpretation, would halt the interpretation. (REXX is generally executed in interpretative mode.)

Nila,
You must take care the case of an infinite loop in the program itself as Bond says. Yes, TIME parameter can be one way of controlling infinite loop problem.

Nila,
Another thing that you could do is,

Hi Cogito, Bond
Thank you for the responses.
Now I can control the infinite loop problem.

Same as in my earlier post.

Test the value of z; in a loop or in any part of the EXEC. If it is beyond the limit you have decided, then exit the EXEC.

Ravi,
Honestly, I fail to understand your question. Could you kindly elaborate your requirement? Maybe, I could more info then.

Ravi,
So, what you want to do is, limit the foreground execution time of a REXX EXEC. Am I right? IF yes, then testing the elapsed time is the only way I can think of.

Sorry, I believe there is no point in dragging further.
