Thanks Jay and others,
I said earlier that
Code:
#byte portb = getenv ("SFR:PORTB")
did not work and I changed all portb references to input_b() which worked. Well I went back to the getenv statement and it does work. I don't know what I did wrong but something obviously.
With
Code:
#byte portb = getenv ("SFR:PORTB")
  long pntr;
  pntr = &portb;
  sprintf (buff, "portb = %x", pntr);
in appropriate places in the program I get "portb = 0d" displayed so getenv definitely works showing the correct address for portb. I will switch to input_b() and forget bad habits I learned in 2002.
I will implement all the lessons learned here, thanks to all.

If you also program the 18F parts - you REALLY want to abandon direct I/O register access, because it is different on that chip.

The glory of CCS is that their intrinsic functions like input_b() and output_B()
as well as timer setting , pwm and most other PIC function components , compiles the same code transparently across different parts and even differing families of PICS ..

You were guilty of the same lapses i committed when a newish user - fresh out of assmbler only PIC work. CCS is just so much better
