RE: %Scan (Again...)

Jim,

The question is actually does the string "" contain the substring "Hi
there"... and that's definitely not the case.  However, when an empty string
is involved they both bomb.

Your case can be argued about, but my example should definitely return 0 in
my opinion.

Kind regards,
Paul

Well, tell me, does the string "Hi there" contain the substring "" ?  Kinda
like dividing by 0, there is no real answer.  Any string could be considered
to contain a null string, or could it?  Depends on your point of view.

I wouldn't mind searching for a null string to bomb out, as I wouldn't mind
a divide by zero bombing out.  Any result a divide by zero gives could be
considered wrong.  Is it 0 or infinite?  Null contained in a string, is it
the first position, all positions or no positions?

That is something that should be checked in code, not the function.

Regards,

Jim Langston

Hi Barbara,

I just opened a problem report if that is of any help.

As far as the 'needle' is concerned... why not return 0 as well ?

Kind regards,
Paul
