the assignment is:
Create a macro named mWriteNumber that writes a signed integer to the console output.
Use the WriteInt procedure in the Irvine32 library. The argument passed to the macro can
be a byte, word, or doubleword. Use conditional oeprators so that the macro adapts to
the different sizes of the argument. Write the main code to test the macro, passing
arguments of different sizes.
i'm not asking for codes but just ideas on how to approach it. any suggestions? thanks.

        IFE rv ; if not a register use SIZE 
            IF SIZE var EQ bytes
                EXITM <1>

            ENDIF
        ELSE   ; it's a register
