Bill,

Guide 9.0 resides in my D:\Program Files\Guide9 directory. I loaded the entire two-sided USNO DVD into the A2 directory on my D drive. The directory contains the 6 USNO support files and Z001-Z360. I opened GUIDE.DAT and added:

A2_PATH=15.0;d:\a2

to the bottom of the file with Notepad, for USNO to kick in for mag 15 and dimmer, but USNO is not being displayed. Appreciate any thoughts...

Tom
