LEAVE           High Level Procedure Exit            Flags: Not altered

LEAVE                                                CPU: 186+

        Logic   MOV eSP,eBP
                POP eBP

    LEAVE reverses the action of a previous ENTER. By copying the
    frame pointer to the stack pointer, LEAVE releases the stack space
    used by a procedure for its local variables. The old frame pointer
    is popped into BP or EBP, restoring the caller's stack frame. A
    subsequent RET nn instruction removes any arguments pushed onto
    the stack of the exiting procedure.


    Note
    Some assemblers support LEAVE extensions that force the use of
    SP,BP (LEAVEW) or ESP,EBP (LEAVED) regardless of the segment's
    size attribute (80386+).
