It can reduce 2 cmp to 1 cmp. For example

Code:

 add     ecx,[current_base]
  cmp     eax,ecx
     ja      .finish
     cmp     eax,'0'
   jb      .finish

You can do something like

Code:

lea edx, [eax-'0']
cmp edx, [current_base]
ja .finish

Ok, I see... I got:

Code:

mov     ecx,'0'-1
lea     edx,[eax-'0']
cmp     edx,[current_base]
jae     .finish

Thanks!

Thanks for fixing the bug, roticv! I couldn't figure myself what's wrong...
