How did you know that i should do that?
The warning message tells you where the problem is. Warning[202] \PBP\PBPPIC18.LIB 1239

I looked in the library at the line # indicated by the warning message. In v2.50a there was no problem. In v2.47 this was missing, so it's a simple fix to get rid of the warning.

It also helps if you know assembler...;o]
