Dear Colleagues,

Is there a problem with using macros in relocatable code?  I'm using
MPASM.  I've got a file called "pushpop.asm", which assembles fine and
contains the following:

    push     macro
    movwf    wcopy             ; save w register
    swapf    reg_status, w     ; save status register
    movwf    scopy             ; without altering status bits
    endm

    pop      macro
    swapf    scopy, w          ; swapf status nibbles again and place in w
    movwf    reg_status        ; restores status reg (including bank reg)
    swapf    wcopy, f          ; swap nibbles in wcopy, keeping result in
wcopy
    swapf    wcopy, w          ; swap again and place in w (status
unaffected)
    endm
    end

In my "main" program I have the following:

    extern push, pop, ...

reset:       code 0x000
             goto start

main:        code 0x004

; Interrupt service routine

             push
             ...
             pop
             retfie

; Main program starts here

start:       ...

The problem is that the assembler throws it out with the following:

Warning[207] ...: Found label after column 1. (push)
Error[115]   ...: Duplicate label ("push" or redefining symbol that cannot
be redefined)

It then goes on to report the same thing for all my other macro "calls".

Why does MPASM think it's a label rather than a macro?  The file
pushpop.asm is above the "main" program in the Edit Project box, and
definitely gets assembled (successfully) first.

I did wonder if I should put a "global push, pop" just before the "end"
statement in "pushpop.asm" but then the assembler says:

Error[156] ...: Operand must be an address label (push)
Error[156] ...: Operand must be an address label (pop)

I'm completely flummoxed!  Could anyone possibly help?

Many thanks,

Steve
