First of all, thanks to everyone that responded.

I FOUND THE PROBLEM ! !

These tired old eyes are not what they used to be. Turns out, the Include file REENTERPBP-18.BAS had TWO DOTS between 18 and BAS

(ReenterPBP-18..BAS)

I had copied and pasted the files numerous times, but just perpetuated the problem. Not sure what caused the other warning, perhaps this caused that as well - - Anyway, all is good.

Thanks again for everyone's suggestions
