Okay, silly me had been looking at all the posts for overcoming the A/D features on the "a" ports and nearly everywhere I went, the example programs used ADCON1 = 7. Since I have a PIC18F2525, I have several more A/D ports (?) and needed to set all of these as digital I/O, not analog. Thus, the fix is:

Adcon1 = $0F

BigWumpus, thank you for the guidance.

Hope this helps others!
