Special Characters at the end of a string

[Dave Hannum]

I want to look at the last character in a string, and see if it is something other than a letter of the alphabet, a number or a question mark (?).  In other words, I don't what the last character of a string to be a special character (other than "?").  Would someone be kind enough to show me how this is done.  - thanks

To test, you could use:

if (refindnocase("[^a-z0-9?]$", string)) { do whatever }

To remove any "special" chars, you could modify it slightly into:

string = rereplacenocase(string, "[^a-z0-9?]+$", "");

Not tested, may need tweaking, YMMV, keep head and arms inside the car
at all times, etc.  If you want an explanation or more help.  Feel free
to ask.
