List,
What if $string does not meet the criteria in s/[^a-zA-Z0-9]+//g; can I
get a print statement to say...
if ($string ne s/[^a-zA-Z0-9]+//g) {
print "$string does not meet our criteria...! Please try another
password\n";
}
Is this OK....
Dan

Right. I'd write it as
s/[^a-zA-Z0-9]+//g;
for "efficiency". Or perhaps as
tr/a-zA-Z0-9//cd;
for "clarity". Your ideas of "efficiency" and "clarity" may differ.
