I'm messing with CustomSNMPApp.c and apparently messed it up somewhere (missing #endif). So far, I've printed it out and marked the #ifdef, #else, #endif blocks by hand as lines in the left margin. Since Microchip nests these several deep, it's easy to mismatch them. Is there a source file lister that will do something similar (pair these up through nesting) so I can figure out where I went wrong? I see that MPLABX and Notepad++ let you collapse blocks, but it's still pretty hard to see where the problem is. THANKS!
