Like I said, you want an automated translator. MASM's idea of a "macro" is pretty generous too, eg. ;scales a vector, adds it to another, and stores in a 3rd ;takes edi=dest, ebx=src1, esi=src2, ecx=scale. returns edi=vector vm_vec_scale_add: pushm eax,edx for ofs, mov eax,[esi].ofs fixmul ecx add eax,[ebx].ofs mov [edi].ofs,eax endm popm eax,edx ret Making this work neatly with gas would be, er, fun. And I invite you to understand the code in the div0 directory. 8) > To put it another way , Descent I will make one hell of a splash screen 8) Sure.
