In fasm, how can i generate a symbol like:

sym_1 sym_2 sym_3 .... sym_n

count = count + 1
sym_#count
current_symbol equ sym_#count

In other words, is there a way to convert a number to string?
Or is there an other way to create new, unique symbols?

regards

Use the rept.

Code:

rept 50 x:1 {
  label sym1_#x at x*4
  sym2_#x: mov eax,[sym1_#x]
}
mov ebx,[sym1_15]
mov ebx,[sym2_37]

It works,
... but not for me, because counter-variable x gets not replaced when i use it inside an other macro.

Code:

macro m {
    rept 1 x:0 \{  mysym equ sym_#x  \}
mysym:
}

it creates
   sym_x:
and not 
   sym_0:

You need to escape the # also.

Code:

macro m {
    rept 1 x:0 \{  mysym equ sym_\#x  \}
mysym:
}
