When I was first using CF a while ago, I came across a web page talking
about form validation, and they used this piece of code:
REFindNoCase("[[:digit:]]|[[:punct:]]", myvariable, 1)
I have reused it now and again, but what I have always wondered is what
the [[:digit:]] and the [[:punct:]] things are all about. I know what
they do, but are there more of these? Where can I get documentation?
What are they called? I have looked at various times, but to no avail.
Thanks -
