RegEx - select NOT <some string>

What's the syntax for RegEx to specify that I want to match something that's
NOT a string I specify?
Example: "HELLO WORLD"
RegEx (wanted) = select string that is NOT "WORLD"
Result: "HELLO "

Your example looks more like you want to remove a substring from a string
rather than select a string

Result = Replace("HELLO WORLD", "WORLD", "")

Is this what you mean?

Sorry I couldn't reply sooner.  My IE browser quit displaying the
threads..."error on page"  don't know why.  I finally loaded FireFox (agains
t
Company rules, but so what)

Without seeing exactly what you are trying to do I'm somewhat at a loss.  I
haven't ever used regular expressions.  There may be a pattern syntax that
does what you want.  I thought somebody else might've replied by now.

How would I do it?  The old fashion way... I'd probably break up processing
the string into several steps or loops to remove what I want removed using
the Replace function, or manually, etc.  Maybe not slick but if it gets the
job done...who knows maybe I'd get a pay raise!  (Yeah, right)

Use regex replace - set the regex syntax such that it finds the things you
want to eliminate and replace them with "".
