I'm trying to convert code which worked in masm to fasm.

Here is an example of such a problem:

Code:

format MS COFF

public A

section '.data' data readable writeable

my_data db 000h,000h,000h,000h,000h,000h,000h,000h,000h,000h
A equ my_data + 4

The idea is to have a data area and specify a public name in the middle of it.

Is this possible with fasm or do I have to break my data into smaller pieces and create traditional labels?

Thanks in advance.

hg: use <code> tags (with [] insted of <>) to make your code examples more readable

Use = instead of EQU:

Code:

A = my_data + 4

In general, use = for addresses and numbers, while EQU for text substitutions (which don't apply backwards).
For more details I suggest reading the sections 2.2.1 and 2.3.2 of fasm's manual.

And for readability: if you use symbol (A) as a numeric constant use "=", but if you are using it as a label (placeholder for somewhere in your program) use "label A dword at my_data+4"
