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 |
| Returns: | Nothing |
| 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. |
