I would like to know what bugs you've found
I have had problems with sleep,
also with pins ( I now ALWAYS use the full name ie: if portb.3=0
then.....)
and also a timing problem, out by a factor of five, (count, rctime or
pauseus I don't remember ) at 4mhz osc.

I am not as happy as you are on this one
PBP eats up lots of ram (a big problem on 16c84's)
also PBP has lost a lot of it's automatic functions
that make stamp/pbc easy.

ie: I have just writen a test program to drive an LCD, I also have
buttons connected to the LCD data lines (two buttons at the moment
porta.2/3)
loop:
trisa.3=1
pause 5
if porta.3=0 then
lcdout "button depressed"
endif

result = strange characters on the display ?
fix    = set the trisa.3=0 before the lcdout
This should surely be set by the lcdout command !

And as for tight code, this test program has 11 lines
and outputs only 1 character to the LCD display. ( each character takes
2 words )
It compiles with PBP to 220 words or almost 1/4 of a 16f84 program
space.
22 Words per line ?


loop:
lcdout $fe, 1                        'clear display
trisa = 1                            'porta set as inputs
pause 5                              'wait 5ms
if porta.3 = 0 then                  'test button
trisa = 0                            'porta set as outputs
lcdout $fe, $c0                      'go to second line on lcd
lcdout "D"                           'down button pushed
pause 1000
endif
goto loop
