I guess it might depend on the bigger picture of what you're trying to 
do.  I assume ABCDEF is just an example.   Do you want to exlude 
ANYTHING that is prefixed by '% ' ?

If so, you could simply do something like this in perl in the context of 
a loop:

/^% / && next;

that's assuming it's starting a line.

My point is, I don't know that you've provided enough info regarding 
what you're actually trying to accomplish.

Until later, Geoffrey
