Hi John
you can doit, It is very helpfull to know what are you turning setting or
clearing
when writing the code :-).
here is an example:

#define        _txda           PORT_A,1         ;SPI txdata
#define        _rxda           PORT_A,2         ;SPI rxdata
#define        _we             PORT_A,3         ;write enable/1

I usually do it at the begining of the program.

so if you whant to do : BCF PORT_A,1
              just do  BCF _txda
easier isn't it?.

Hope it helps.
see you.
