I keep getting an "extra characters on line error" error with the structure below and cannot tell where the error is? Can anyone help?

all of the errors are in the struct macro, line numbers 60, 80, 88

Code:

struct FMODDSPDESCRIPTION
       name db 32 dup(0)
       version dd 0
       channels dd 0
       create dd 0
       release dd 0
       reset dd 0
       read dd 0
       setposition dd 0
       numparameters dd 0
       paramdesc dd 0
       setparameter dd 0
       getparameter dd 0
       config dd 0
       configwidth dd 0
       configheight dd 0
       userdata dd 0
ends

The "version" is a macroinstruction (one of the resource ones) and thus line "version dd 0" is interpreted as macro. (Hmmm, maybe I should rename this macro to "versioninfo"?)

ok, I see now, thanks. But now have another problem, the .if macro doesn't except the "jl" instruction, example:

.if dword [eax + lnx.x], l, 1

gives me an illegal instruction error

Works for me, perhaps you've got another conflict?

PS. Changed that macro to "versioninfo" - more descriptive, less conflicting.

I've tried the code with different parameters for the .if macro: a, b, ae, be, g, ge, le, all work ok except l (the letter "L" 'l') Question

Post some minimum source that shows the problem.

The struct:

Code:

struct IntersectPoints
       x dd 0
       y dd 0
       dx dd 0
       dy dd 0
ends

struct definition:

Code:

  lnx IntersectPoints
      times 60 * sizeof.IntersectPoints db 0

code block giving me the illegal instruction error

Code:

     .repeat
             mov     eax, sizeof.IntersectPoints
             mul     [l]
             mov     [addr], eax
             
             .if     dword [eax + lnx.x], l, 1 ;<------ ** HERE **>
                     invoke  RndInt32Range, 0, 3
                     add     eax, 2
                     mov     ecx, [addr]
                     mov     dword [ecx + lnx.dx], eax
             .endif

             mov     eax, [addr]
             .if     dword [eax + lnx.y], l, 1
                     invoke  RndInt32Range, 0, 3
                     add     eax, 2
                     mov     ecx, [addr]
                     mov     dword [ecx + lnx.dy], eax
             .endif

             mov     eax, [addr]
             .if     dword [eax +lnx.x], g, SCREENWIDTH-2
                     invoke RndInt32Range, 0, 3
                     add    eax, 2
                     neg    eax
                     mov    ecx, [addr]
                     mov    dword [ecx + lnx.dx], eax
             .endif

             mov     eax, [addr]
             .if     dword [eax + lnx.y], g, SCREENHEIGHT-2
                     invoke RndInt32Range, 0, 3
                     add    eax, 2
                     mov    ecx, [addr]
                     mov    dword [ecx + lnx.dy], eax
             .endif

             mov     ecx, [addr]
             mov     eax, [ecx + lnx.x]
             add     eax, [ecx + lnx.dx]
             mov     [ecx + lnx.x], eax

             mov     eax, [ecx + lnx.y]
             add     eax, [ecx + lnx.dy]
             mov     [ecx + lnx.y], eax
             inc     [l]
     .until  [l], a, 5

I guess you are using local variable of the name "l", thus "l" inside the procedure gets replaced with the address of that variable. Possible solution: use other case to avoid conflict:

Code:

.if     dword [eax], L, 1
