RE: Memory Leaks in RPG (was: Is RPG 'DEAD")

I'm not an expert on such things ... but
wouldn't the memory be recovered when
the program ends since *INLR is on?

I would expect not. What if you'd passed a pointer to that memory to another program (perhaps your caller) before returning? It's usually these what-if situations that make memory leaks so difficult to prevent.

Come to think of it... Can I save a pointer to memory in a userspace? And if so, is that pointer valid in another job? If so, can I even rely on an endjob to reclaim the memory?

is a memory leak. The leaked or lost memory will persist until the
job ends or the activation group is reclaimed.
