QueryFile/SaveQuery question

[Eric Steele]

Hi,
 I'm trying to write a function a few features that match some criteria and
then allow the user to pan/zoom to look at them further, all the while
keeping them highlighted. I have it selecting the features, but I haven't
had any luck making them persistent.  I assume I want to do a
SaveQuery/QueryFile with these. Can anyone give me an explanation of how
they work, or at least point me to any relevant information?
Thanks,
Eric
