Re: easy (should be) perl question..

The following works for me.

> $str = "ABC";
> if ($str =~ /\D/)
>  {print "non-digit\n"; }
> else {print "digit\n"; }

I think the space characters inside your
slashes were causing the grief.

When setting your test string, you might want
to use quotes to avoid confusing yourself.
$str = 12x3
is not the same as
$str = "12x3"

But yes, if "ABC" is changed to "123" (incl the
double-quotes), the above will correctly report "digit".

BTW, altho' this question might not be *entirely* off-topic
for hwg-servers, it might be better off posted to a Perl
listserv anyway, IMHO.
