'MPASM bugs with #define'
1995\06\22@005001 by Greg Solberg

Hi,

I use Microchip's MPASM v1.10.  Anyone else have problems with #define?
For instance, I compile the following code:

   #define     FOO(a)  (a)
   one equ     FOO(1)
   two equ     FOO(1) + 1
   three       equ     FOO(1) + FOO(1) + FOO(1)
   four        equ     2 + FOO(2)
               end

And I get the following in the list file:

                    0001  #define FOO(a)  (a)
 0001               0002 one     equ     FOO(1)
 0001               0003 two     equ     FOO(1) + 1
 0001               0004 three   equ     FOO(1) + FOO(1) + FOO(1)
 0004               0005 four    equ     2 + FOO(2)
                    0006         end

The values computed for labels "two" and "three" are wrong.  The basic problem
seems to be with using a #define macro at the beginning of an expression.

Does anyone else have this problem?  Does Microchip know about it?  Anyone
have some nice work-around?

Thanks for your help,
Greg Solberg
