This is one of several calls by which a program can terminate execution. It informs DOS that the program is complete and that occupied memory should be released.
|Action:||On execution the call restores vectors for INTs 22h to 24h from the program's PSP, flushes any buffers and transfers control to the terminate handler address.|
|On entry:||CS = Segment address of PSP|
|Notes:||The preferred termination method is INT 21h function 4Ch. Since this call has a memory addressing limit of 16 bits, (64k bytes) it is of limited use, and cannot be used in an EXE program.|
