The regular expression syntax that WinRunner supports is defined in the
WinRunner User Guide under Creating Tests which has a topic called "Using
Regular Expressions".

It appears that the Regular Expression evaluator that is free on our website
support all the WinRunner syntax except the "!" operator which tells
WinRunner that the following text is a regular expression.

I hope this helps you.
