Re: Dynamic Storage -- RPG400-L

Interesting that they want to go on doing something that often doesn't do what people think it does (RCLRSC) and then change CLPs to CLLE for no reason. You can debug a CLP as easily as a CLLE - with the one exception of not being able to directly use SEPs on OPM programs.

But anyway, I gave you the answer in my earlier response.

RCLRSC really doesn't do much at all (or at least much that needs to be done) - and can cause all sorts of "interesting" issues when in an ILE/OPM mix.

RCLRSC is used extensively here, so they plan on staying in the default activation group. CLP's are being converted to CLLE's for debug purposes.

My question is does RCLRSC free dynamic (heap) storage or just static storage?

Walter,
Just a guess, but since you mention CLLE, I think you want to think about using RCLACTGRP in place of RCLRSC - which is an OPM command.
RCLACTGRP should be used for ILE.

I have a quick question concerning the release of heap storage that we use for dynamic sizing arrays. I understand that heap storage is released with the RPGLE dealloc command. We have a case where we load dynamic arrays in the *INZSR routine and leave LR off so the arrays are only loaded once since this program is called multiple times. The program is called in a CLLE stream running in the default activation group. When the RPGLE program finishes being called multiple times, will a RCLRSC command free up heap storage? I've read in multiple places where RCLRSC will free up static storage, but no mention is made of heap storage. I could call the RPGLE program one last time with a flag that would do the deAlloc, but if RCLRSC does it, then no need to do the last call.
