This is my first posting, so please try to bear with me. I am experiencing a great deal of difficulty with getting a TSR program (I have written) to be able to change the memory it is using after it has terminated. Under some circumstances I want the TSR to get smaller and then to recover the memory it released, if possible. When I want it to shrink I set my PSP to my original PSP and then issue a SETBLOK. The TSR does shrink but this is the beginning of the problems. In order to recover the lost memory I tried to simply SETBLOK it but the block of memory I released is not marked as FREE, instead it is owned by DOS and hence cannot be allocated (even though it is the last block in the system and is not in use). I proceed to mark the block free manually and then the SETBLOK will work. All is well until I try to get the TSR out of memory because all the work is done. Now future memory allocations have the parent PSP in the memory block marked as my TSR not DOS. (I get this info from MKS Toolkit ps command). Any ideas about how to do this??
