RETCODE          Procedure return                                   Extension

  RETCODE [pop_value]

    Generates either a near return (2-byte displacement) or a far return
    (4-byte displacement) depending on the size of the memory model declared
    in the MODEL statement. It is the equivalent of RETN for models with
    NEAR code, RETF for models with FAR code.

    The optional pop_value specifies a value to be added to SP, which is
    equivalent to popping the specified number of bytes from the top of
    the stack.

    The RETCODE statement does not generate any procedure epilog code.
