[texhax] Highlighting text within "verbatim"

[Craig A. Vanderborgh]

Hello Everyone:

I am trying to figure out how to highlight text within the "verbatim"
environment of LaTeX.  Basically, I need to emphasize certain lines
(perhaps with a grey rectangle) of text.

Is there a way to do this?  Please advise..

Thanks in advance,
