They are both 100% valid.
One is used for USB, the other is used for NON USB programs.

Thank you Darrel, you have sharp eyes and clearly a brain behind those eyes!

I'm back from a nice one week refreshing holiday, with new energy...

After correcting my own mistake (overwriting 18F4550.bal) there was “real” progress , reduced the amount of errors [126] and warnings [220] to only four, but brought back “an old problem”...
“ERROR: Macro USBINIT? Not found in macro file”
and those three other errors also (usbservice,usbin,usbout).

Searched around this thread “ERROR: Macro USBINIT? Not found in macro file” and read every mail that was somehow related to this situation and the only difference I could find was that PBPUSB18.MAC should be in C:\PBP\USB18 directory. I checked that and did not find PBPUSB18.MAC file in C:\PBP\USB18 directory. Why did my USB work earlier without that file in USB18 directory?

So to try something I dropped a copy of it there, as advised somewhere around here, but unfortunately it did not help this kind of an old problem... I had USB working earlier with PBP but what now when trying to get PBPL working?

Any suggestions how to proceed from here?
