Why is the machine status saved during an interrupt call and not during a subroutine call?
What will be an ideal response?
When a subroutine is called, the status word may be changed during the execution of the subroutine. However,
the programmer can save the status word in a subroutine (or across a subroutine call) if he or she wants to.
Interrupts are external and asynchronous. They can occur at any time. Consequently, it is necessary that the
status word be saved automatically when an interrupt occurs.
