The expression [^a-z0-9] means match any character that is NOT a-z or 0-9. That will
return only special characters. You probably want
REFindNoCase("^[- a-z0-9]*$", str)
This will return 1 if the following happens.
at the start of the string (the carat) look for a dash, a space or any character of
a-z or 0-9. Match as many of these as you can until the end of the string (the dollar
sign).
"New York" - N is the first character at the start of the string. There are only
letters and a space. The k is the last character in the string. The function will
return 1 (success).
"Wilkes-Barre" - W is the first character of the string. There are only letters and a
dash. e is the last character in the string. The function will return 1 (success)
"[EMAIL PROTECTED]" - m is the first character in the string. There is an at
sign in the string. The function will return 0 (failure).
