I'm trying to stop a BATCH program for a few secs (1 or maybe 2) but I didn't find any commands/syntax that can help me.

So, are there any commands that can stop the process or delay it?

No. I want to stop the program when he's already running. Not 'outside' in the JCL.

Here's an example. But this one is in CICS

Code:

MOVE  3                     TO  WS-TIME
                                       
EXEC CICS                               
     DELAY                             
     INTERVAL (WS-TIME)               
     RESP     (WS-STATUS)               
END-EXEC         


I need something like that, but for a batch program.
Thanks for the help.

COBOL doesn't have a WAIT command so you would have to write an assemble program and call it from your COBOL program.

Hello,

What is going on that the "batch program" needs to wait for?

What should happen when the "thing" being waited for never happens (and that will happen).

As was asked before and not yet answered - what business requirement will be supported by this?

Should we wait for a reply?

Unfortunately, i'm paused just now. . .

When resumed, i'll determine if i need to wait. . .

Maybe i just need a break icon_wink.gif

For pausing a Batch program you can use.

Code:
STOP 'Press Enter to continue'.


The above code will pause your program and will require operator intervention.

But, whenever such condition arises I will suggest you to use Accept and Display verb

Do not use STOP literal statement in programs compiled with THREAD option.

Hello,

Please do not use STOP or DISPLAY/ACCEPT unless you want the Operations people coming after you to do damage to you. It is not acceptable to do this on today's systems.

Most systems will not permit such code to be promoted to production, so there is no use wasting time testing it. Some systgems abend the job.

Hi
I think that the following MVS Service will do what you want

(BPX1SLP, BPX4SLP) -- Suspend execution of a process for an interval of time

See this link:
