am trying to generate some more efficient code from my C routines. I
have found that the following type of while loop, which is hanging
around until a bit is set generates about ten lines of code.

while (PIR1bits.SSPIF==0);

It might be worth trying

while (!(SSPIF))
{
}

or while (!(PIR1&(1<<SSPIF))

With my 'C' compiler the last one produces 3 lines of code.

I have always been a few Dendrites short of an Axon and believe me it shows.

Light travels faster than sound. That's why some people appear bright until they speak!
