Actually, I hate to say this, but I believe that the metacompco way
is actually better in it's own way.  For instance, suppose I had the
following macro:

Blah    MACRO
\10: dc.b 0
\11: dc.b 2
\12: dc.b 5
        ENDM

..and then made this call..

   Blah   Lbl

I would expect my generated macro to produce this code:

Lbl0: dc.b 0
Lbl1: dc.b 2
Lbl2: dc.b 5

In the way that Mr Gibbs has done this, there is no way to have another
number immediately follow the parameter within the macro (unless I am 
mistaken..).  Therefore, having your parameters limited to a single char- 
acter would be advantageous.

Then again, having unlimited passable parameters is nice, too :)

(wishing I even HAD an 030 or 040)
