Thanks, Pekka,  there are a couple of tricks there that I hadn't thought of.
I like the idea of defining the pullups bit and setting it directly - there
are a number of other bits that this trick would work well on.  Usually I
just dive into assembler for these tasks.

Despite what others say here, I'm beginning to like CCS as well.  Most of
the problems I have had were traced to the keyboard entry algorithm (i.e.
me+ACE- +ADw-G+AD4-) not to the compiler.

Lawrence,
CCS uses its  own function to portb pullups, see page 51 in the CCS
manual or  table of contents:
port+AF8-b+AF8-pullups(true)+ADs-   // If not PCM be sure to use external pullup
s

or you can use direct memory manipulation
+ACM-byte OPTION +AD0- 0x81
+ACM-bit pullups +AD0- OPTION.7

and then
void main ( void)
+AHs-
setup+AF8-counters(RTCC+AF8-INTERNAL,WDT+AF8-2304MS)+ADs-
pullups +AD0-0+ADs- // enable pullups
...
+AH0-
You can look very easily after compile in assembly:

I think like CCS PIC-C-compiler in very good
