Hello,
I believe you don't need the /g modifier in that regexp since a single
match to an unwanted character is enough.

I tried the following code to test for bad characters but keep
getting my error msg though the values passed do not contain chars
that are not "A-Za-z0-9_@.-" (I also reread my last post and found
that my English articulation was very poor, I'm grateful that anyone
responded!).

Err, you mean "accept only alphanumerics AND @ and .".

How would you correct this expression to accept only alpha/numeric
except the @ and . (period) symbols? In other words, how would I add
multiple chars to exclude to the regex?
if ($name=~/^W&&[^@]]+$/)
{ print "Only the @ and . characters are allowed";
}
> if ($name =~ /^[\w&&[^0-9_]]
This is most definately not the same...
\w is equivalent to [A-Za-z0-9_]
there's a basic regexp tutorial here:
http://japh.nu/index.cgi?base=regexes
it also deals with (custom made) character classes, special symbols in
regexps etc,
maybe it's beneficial to you.

This guarantees that it *starts* with letters. Add a $:
$name=~/^[a-zA-Z]+$/
Now i
The expression you're using will match letters at the beginning of a string,
but will allow for other stuff at the end. To avoid this, put a $ at the
end of your regex. Also, [a-zA-Z] can be replaced with \w, which does the
same thing.
So, you have
$name =~ /^\w+$/

That doesn't check to make sure the string ONLY has those. It checks to
see whether it STARTS with them.
