In other words, I want to use AllocRemember with a single key for all my allocations, so I could free up all the memory in one shot upon exit from my program. But during the course of my program execution, I would like to free up selected chunks of memory, (without freeing up all of it). Is that doable?

I wrote a routine to do this; I'll see if we (C-A) want to release it. To Ken Baer: You said you have to "keep track of all your keys". Are you sure you are using AllocRemember correctly? You only need to declare one key (one instance of a pointer to a Remember structure). Then you keep passing the address of that key to subsequent calls to AllocRemember, and finally to FreeRemember. If you are declaring a key for each allocation, you are missing the whole benefit of AllocRemember. -- Adam Keith Levin -- CATS Commodore-Amiga Technical Support 1200 Wilson Drive / West Chester, PA 19380 (215) 431-9180 BIX: aklevin UUCP: ...{amiga|rutgers|uunet}!cbmvax!adam
