My apologies, I must have misunderstood your question about submatch(). I thought you had not read the help because:
1. I thought you were trying to use submatch() with a match() or matchend() call, since you did not mention using substitute()
2. You did not seem aware of the optional 4th argument to match() and matchend() which is documented in the help
3. You did not seem aware of matchstr() or matchlist(), which are linked from the help topic for match()
submatch() does not do any substitute by itself. It is as way to access a captured group in the replace text for a regular expression applied using the substitute() function, or the :substitute command, either of which can be manipulated to not actually make any textual changes.
