I was able to install PBP (v2.50B) in MPLAB (v8.10), but with some annoyances.

I am using a 16F88 chip and in MicroCode Studio I modified the default configuration bits using the @ device ..... inline specifier since I was using PM.exe (not MPASM). Apparently MPLAB only uses MPASM. I tried to change to the __Config line, but get errors of overwriting the config byte. I believe this is due to the fact that MLAB automatically includes C:\PBP\16f88.inc which has the __Config statement in it. I tried copying this inc file into the local project directory and commenting out the __Config statement, but MPLAB still picks up the C:\PBP version. Maybe this is a system environmental path declaration issue, but didn't want to change that yet as it might effect other things.

Is the only option to modify the .inc file in the C:\PBP directory? Not a great solution, unless I use the __Config in every PBP program.
