Re: How to properly Ending a background program

Patrik,

The SHTDN rpg opcode has been available from the start, so that should available.

Signals have been available in ILE since V3, so that should also work for you.  I have used them from RPG many, many times.  (I have never used them in PASE, however, not sure why you even brought that up... this is the RPG forum.)

Thanks for any pointers to further documentation, or a short explanation.

Thank you for all your valuable input!

@Alan, @Carel, @Jon: *DTAQ adds more complexity than I want.

@Paul, @Charles: %SHTDN is a very nice one, I'll keep this in mind for newer projects. Unfortunately, it's not available with V4. Yes, I know, I wasn't mentioning this in my initial post. :-)

@Charles: ON-EXIT is a really nice one, I know that exit handler thing from C. Good to know that it's available in RPG, also (but not in V4, as I checked).

@Niels: I expected signals to work "as usual" in C. My question was regarding ILE RPG.

@Thomas: I guess RTVJOBA value ENDSTS works with V4, so this sounds like a favourite to me.

@Scott, thanks for this implicit mentioning of SIGTERM. Do you have some pointers to more information about this facility regarding ILE and RPG (not PASE!)? I know it from Linux programming, and I like it for "no polling needed". Additional: pwrdwnsys/endsbs *immed (as opposed to *cntld) does what to the processes? Kill -9?

Thanks again, folks!
