Thanks Ken and Steve,
for the variety of clean solutions you offered. Just out of
curiosity, I should like to return to a point mentioned by
Ken :
>If you must work character-by-character,
>use character constants (e.g. >'0' or '9')
In that (unlikely) situation, how would I test, say, equality
of characters ? For example, if I needed to know whether
character number j in aString is '7', writing
([aString characterAtIndex:j]=='7') wouldn't work, would it ?
