OK, I only made it "Regex" because I can't physically say the 
word "RegExp" ;)

Actually, with my existing code it's shorter:

MyRegExp = NEW RegEx("...", "...")
PRINT MyRegExp.SubMatch(1)

But I see the value of making it a virtual class.  I almost did 
that originally but I just wanted to get the code working.  Is 
there any way I can make a "default property" of a virtual class 
such that

MyRegExp.Submatch[1]

returns the submatch text the same as MyRegExp.Submatch[1].Text, 
but

MyRegExp.Submatch[1].Offset

would still work?

Thank you, I certainly will be consulting the Qt component for 
all this "virtual class within virtual class" stuff.

I don't see how you could do it anyway unless I made a static 
version of the class.  I have made a module (which i added to my 
local copy of the IDE) to do a match or replace in 5 or 6 
different ways anyway, so maybe once gambas code can be used in 
components I can make a gb.pcre.match component or something.
