An alternative is the string comparison I normally use:

	cmpstr(s1,s2)
0: if equal
>0: if s1 > s2
<0: if s1 < s2

abs(cmpstr(s1,s2)) is the number of chars compared:
  s1[ abs(cmpstr(s1,s2))-1 ] != s2[ abs(cmpstr(s1,s2))-1 ]
  if cmpstr did not return 0.  Normally this function returns just
  about any information I need, and it is usually not very hard to
  make an extremely fast version in assembly.
