hi vbVeryBeginner

here code from masm32 package and converted 2 fasm syntax

Code:

proc atol lpsrc

   xor eax, eax
   xor ecx, ecx
   mov edx, [lpsrc]

   sub edx, 1
  @@:
   add edx, 1
   cmp byte [edx], 32
   je @b
   cmp byte [edx], 9
   je @b

   mov al, [edx]
   add edx, 1

   .if al = '-'
       add ecx, 1
       mov al,[edx]
       add edx, 1
   .elseif al = '+'
       mov al,[edx]
       add edx, 1
   .endif
   push ecx
   xor ecx,ecx
@@:
   sub al,'0'
   jc  @f
   lea ecx,[ecx+ecx*4]
   lea ecx,[eax+ecx*2]
   mov al,[edx]
   add edx, 1
   jmp @b
@@:
   mov eax,ecx
   pop ecx
   shr ecx,1
   jnc @f
   neg eax

ret
endp

atoi will be something like this

Code:

int _atoi(char *s)
{
        UINT    i=0,n;

        for(n = 0; s[i]; i++) n = 10 * n + s[i] - '0';

        return n;
}
