That sounds reasonable... thanks Robert! AES?
Searching will be fine since it's only done once by the installer. 

Yes, the code is, um, taking on a life of it's own. I've been at this program
for two years now (just in spare time) but it still feels like I'm just
beginning. It's grown from one BIN and one BAS program to... well, currently
the installer copies three of the six executable modules and two supporting
binaries and then creates error message data, FOG Help, graphics data, and user
configuration files... plus whatever fonts I've scrounged, and still a little
room for some of my old PMODE graphics, just for fun!

cheers,
Bob
