Rory,

Thanks for the ideas, I agree with your best method and may do it that way.
(Also, hadn't heard that 'sleep can be defined to wake up with signals...')

What I'm building is an rpg listen program to check an ifs folder
for any files in it. I'm not currently using a data queue for doing this,
I'm using the sleep api.

Only thing I've thought up myself is when I want to end the listener
job/program,
drop a specifically named file into the folder, ... named 'QUIT.TXT' maybe,
Then have the listener check for that file's existence each time it polls,
and if it finds 'QUIT.TXT' file in the folder, end gracefully.

Whatever your normal shutdown mechanism, you still might want to do clean up
in the event your job is ended the old-fashioned way. For example, some
folks are fond of using PWRDWNSYS *IMMED to initiate an IPL. Here are some
APIs you may find useful:

Send Scope Message (QMHSNDSM) API
Register Call Stack Entry Termination User Exit Procedure (CEERTX) API
Register Activation Group Exit Procedure (CEE4RAGE) API
