Word-oriented GREP

[Taed Nelson]

When I use the command "grep V\[0-9\]\[0-9\]\[0-9\] fred.c" it returns
	#define VERSION "V002"
  or somesuch.  What I would really like is just the string of characters
  which matched:
	V002

I thought about it for a while, and I couldn't come up with anything;  even
  AWK seems to offer no nice way of doing it, but this seems like something
  that is at least somewhat common...

Does anyone have any suggestions, preferably limiting the solution to SH or
  CSH, and by not using uncommon tools such as PERL?

Thanks a lot!
