Greetings,

I need to limit a string length between 1 to 2
characters. For the pattern I have
...
RE.IgnoreCase
RE.Pattern = "[a-z]{2}"

I want to capture like "a" or "aa" but not "aaa", or
capture "ab" ok, but not "abc" (more than 2 chars)
or "abb", etc. I can never figure out how to limit the
number of chars occuring in the pattern. Any suggestions
appreciated how to be able to limit the length of the
string between 1 to 2 chars (or just what the rule is for
limiting how many chars can occur in a pattern).

Thanks,
Steve

Well, I stumbled onto one pattersn that appears to work
for what I need

RE.Pattern = "^([a-z]){1,2}$"

I just don't like the idea that I am hacking away to get
this. Is there a rule? Or are they all just hacks?

If documentation = rules then
goto " http://www.yqcomputer.com/ "
install
read "VBScript / Introduction to Regular Expressions"
end if

Do you want to truncate strings greater than 2 characters, to 2 characters
or do you want to only return characters that are 2 characters in length?
And, are you accepting any characters or just A-Za-z?

If this written in VBScript blocks or ASP?
