The MATCH (or LIKE) operator could set a few properties in the 
background, so the code would be something like this:

	IF MyStr MATCH "(\w+)" THEN
	  PRINT RegExp.SubMatch(0)
	END

I don't know if this is an elegant solution but would be handy. :)

I think it should operate directly on the variable; that's what we 
usually want, isn't it?

It could return the number of substitutions, so we could write:

	IF REPLACE(MyStr,"fox","dog") THEN
	  ' 1 or more substitutions
	  ...
	ELSE
	  ' zero substitutions
	  ...
	END
