In my experience different ANSI 'C' compilers for the PIC aren't equal=20
either in the assembler they produce or the way in which the syntax is=20
used. There are some things in assembler that just can't be produced by a C=
=20
compiler with reliability.

Structs seem to have slightly different implementations between compilers,=
=20
and as yet I've found no compiler that will test if bit 3 is set in a loop=
=20
variable as a short cut for looping 7 times.

The only book I can think of that has some Microchip and Hitech 'C' code in=
=20
it is John Peatman's Pic 18F452 book, and even then it is an add on at the=
=20
end of the book. Code is available for download from his website=20
(www.picbook.com).
