there is Very Happy, try cutting each else if until it will be a valid expresion, so you can isolate the "invalid part" =D

Code:
if xmm0 eqtype al
 display "WTF!"
end if    
Output ---> "WTF!"

For me, macros=yuk

Memory zeroing can be 3? bytes shorter by using "and [var],0"

WTF

How do I tell if something is an xmm register then?

Look for "in" in the fasm manual.

Code:
use64

macro   zero    var{
   if      (var eqtype rax) | (var eqtype eax) | (var eqtype ax) | (var eqtype ah) | (var eqtype al)
           xor var,var
 end if
}

zero    eax
     

this compiles very fine for me.

Reminds me of a bash.org quote about googling for 'the who'
"'the' is a common word and has been ignored"

It is easy to find as long as one does not naively search directly for "in", that would just be nuts.

539 "in"'s in the pdf. Is there a tutorial specifically for macros?
I usually don't like using them (except in really basic situations) but seeing some of the things they can do I am willing to become a convert...

>that would just be nuts
Yeah, but what else to search for?
