I use fasm 1.73

My problem not defined name.
For example i have two variants one proc Draw3D.
Some time in my program i use first or second variant proc Draw3D.

In first variant proc Draw3D not have posA dd 0,0,0,0
Second variant proc Draw3D have posA dd 0,0,0,0

In main code i do:
mov [posA],10.0

How fix automaticly this and not rewrite hands my code ?
My idea macro check if not defined posA then posA equ Val1 else not redefine.

One or two names not hard, but check many names(i have 400 names) its problem.
If write in code for all names this:

Code:

if defined posA
mov [posA],10.0
end if

If to be to lazy to check each:

Code:

macro ifcompilablevar statement& {
        local a
        match instr size_spec[var]=, value,statement \{
                a = $-1
                if defined var
                        statement
                end if \}
        match instr reg =,size_spec[var],statement \{
                a = $-1
                if defined var
                        statement
                end if \}
                if ~defined a
                        statement
                end if }
                       hello: ; comment hello or world and see difference
ifcompilablevar mov dword [ hello+world ] , 1
                       world:

size specifiers could be skipped if all vars would be defined as vars not as unsized labels.
