Problem resolved!
Many thanks to Xiaofan, Dario, and ultimately Ken Pergola, whose post in 
the Mchip forum described the
process Xiaofan referenced.  I did not find the post during my searches 
because the subject dealt with text substitution and
I was looking for port/pin references.
I am still writing code in assembly, just using the C30 toolsuite to do 
the build.
My code now works with the #define for an individual port pin!
I am surprised that the functionality present in MPASM has not carried 
over into ASM30. This was a work around
I would never have figured out on my own. Now on to the project at 
hand...a small autonomous hobby robot.
Many thanks to all who replied with helpful ideas...much appreciated!
