I think I'm using Enterprise COBOL for z/OS.
What's a technique to emulate the functionality of, for example, the standard C library's sleep() function?
回答1:
Probably the easiest method is to use the Language Environment callable service CEE3DLY or CEEDLYM.

I don't know whether you have found your answer or not.
There is an IBM program that enables the machine to sleep ... or to wait : its name is ILBOWAT0.
Here is the link of a very good example on how you can code it : http://www.mvsforums.com/helpboards/viewtopic.php?t=2008&highlight=delay
In this example, WAIT-TIME is in seconds.
