I'm writing a TSR program. It can already stay resident normally, but I don't know how to make it exit and free the memory. The exit routine I wrote now can restore the interrupt, but the program is still there, and if I run it again it will use another location.
I'm a newbie, and I really don't understand memory management and allocation under DOS, so I don't know what to do. Experts, please give me some advice! Thanks in advance!!!

Record the memory segment of your own TSR code, then use one of the functions in int21 (can't remember which one) to release it.
