Looking a lot more organised Sean - that's good progress for
a day

Just a couple of things. As you get to know the registers better
you could cut down on the BANKSELs. For example PortA,
PortC and TMR0 are all in bank0 so

BANKSEL PORTA
CLRF PORTA
CLRF PORTC
CLRF TMR0

 is sufficient instead of

BANKSEL PORTA
CLRF PORTA

BANKSEL PORTC
CLRF PORTC

BANKSEL TMR0
CLRF TMR0

==================

You can define a name for a bit in a register (such as a pin)

#define led porta,1

would allow you to use the expression

BCF LED

instead of BCF PORTA,1
