Just trying to understand Info in Library Files. Below is a capture of 18f23k22.h file. What is the relationship of these numbers and the port outputs? They don't appear to be the equivalent of the Hex address.
Code:

#define PIN_A0  31744
#define PIN_A1  31745
#define PIN_A2  31746
#define PIN_A3  31747
#define PIN_A4  31748
#define PIN_A5  31749
#define PIN_A6  31750
#define PIN_A7  31751


Thanks
Kevin

They're not.... you can use the 'search' feature here and find a few posts about it. It's 'shorthand' for the Compiler to know which pin of what port.

Convert the CCS pin numbers to hex. The lower 3 bits are the bit number
and the upper bits are the port address, shifted left by 3 bit positions.
