I have a little question.  On page 8 of the note "The
80386SX Processor Bus and Real-Mode Instruction Set",
it says the processor will push the flag register, CS
and IP when an interrupt occurs, use IRET instruction
to pop the IP, CS and flags register.  However, on the
subrountin printc of the example on page 9, after int
21h, iret is not called.  Then, wouldn't pop dx will
pop the content of IP previously stored to dx, pop ax
will pop the content of CS previously stored to ax,
and ret will pop the content of the flag register
previously stored to IP?  Thanks in advance.
