I personally don't like macros that look like actual instructions. An experienced programmer could look for a bug all day long and not find it because they don't realise that mov PORTA,03 corrupts W. If I had to choose a name for such a macro it would be something like _init PORTA,3 or _Store 3,PORTA or _Set PORTA,3 or _Poke PORTA,3. The underscore being there to remind me that it is a macro. I know that MPLAB differentiates by changing colour but that is lost when using a different text editor or posting the code on the internet etc.
Anything is OK if it's for your own personal use, if you intend publishing it then I think the possible confusion weighed against saving 1 line of typing just isn't worth it.
