PROGRAM TERMINATION ADDRESS

Desc

This vector specifies the address of the routine which is to be given control after a program is terminated; it should never be called directly, since it does not point at an interrupt handler

Notes

This vector is restored from the DWORD at offset 0Ah in the PSP during termination, and then a FAR JMP is performed to the address in INT 22. Normally points at the instruction immediately following INT 21/AH=4Bh call which loaded the current program
