fasmw 1.73

Code:

macro ode_ name,pr=0 { invoke name
      mov [eqToData+_nxt_*4],eax
      ;nn equ _nxt_
      match h,_nxt_ \{ _#name\#\h equ eqToData+h*4  \}
     
      if pr = 2
         display _nxt_+48
      end if
      _nxt_ equ _nxt_+1      
      } 
;in code
pData dd 20 dup(0)

eqToData equ pData                ;set out [pData],eax
        _nxt_ equ 0 

ode_ dGeomTriMeshDataCreate,2          ;this ok
mov eax,[_dGeomTriMeshDataCreate0] ;this ok
        ode_ dGeomTriMeshDataCreate,2  ;but this fasm error !    
mov eax,[_dGeomTriMeshDataCreate1]

Error: pData+0*4+1 equ pData+0+1*4

Don't you need to use that trick - to do math in the preprocessing stage?

Code:

      rept 1 h:_nxt_ \{ _#name\#\h equ eqToData+\h*4 \}

... you don't want the text of _nxt_, but its value.

The problem is "_nxt_ equ _nxt_+1".

You get _nxt_ with the text "8+1+1+1+1+1". equ doesn't do arithmetic, it only appends +1 each time.

Use rept.

Code:

rept 1 x:_nxt_+1 { _nxt_ equ x }
