Bulk source search ignoring commented-out code (iSphere special?)

I posted a similar message in Midrange-L, but then remembered iSphere's
Source File Search, and wondered if the function I'm looking for (below)
could be integrated into this.

I need to do a bulk search of source (ala FNDSTRPDM) but with the ability
to ignore all comments.

I'm guessing this is custom-written app, but it seems to be that this would
be a valuable tool for many programmers, especially for those in shops
where code is never deleted outright, but is commented-out.

Specifically, I am looking for all usages of '*MDY' (and other formats
utilizing 2-digit years).

Has someone already invented this wheel?
