If you've got MCS setup to dump out a .lst file with all the options turned on (usually fairly HUGE files), you can usually scroll thru it or search it for the phrase 'ERROR', then using a bit of deductive logic, can usually trace that back to your original problem...whether it be a problem with the typist, an include file, a macro, whatever.
The warning message tells you where the problem is. Warning[202] \PBP\PBPPIC18.LIB 1239How did you know that i should do that?
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]
It may go back a few versions, but I didn't check back any farther than 2.47.
