I want to portable my tasm progs to fasm.
In tasm I use:
mov al, array_b[cx-1]

And in fasm:
mov al, [array_b+cx-1]

But I recive this error message:
error: reserved word used as symbol.

But when I use mov al,[array_b+di-1] - all Ok.

How to solve this very little problem? Shocked

Are you sure that it was with cx? You can use only bx, si and di (even in TASM or any other asm on x86)

I amazed that instruction could be assembled. Could you paste the hex values for the instruction?

Maybe TASM assemble this [cx] as [ecx]. There is imposible to use 16 bit CX for addressing.

Regards.
