Homing XYZ on pin 10 and A on pin 12

Are there standard signal names for the homing portion of a hal file. I'm trying to configure my homing routine with shared pins for XYZ on pin 10, and A axis on pin 12. I'm using parallel port configuration tool. I tried changing the hal file but haven't been successful. I'm assuming I need to name (rename) a "net" input signal and pin assignments but I'm not finding the right place to read in the documentation- to learn it. Could someone point me in the right direction? The names I'm referring to are like home-all, home-x, home-y,etc.... Standard or arbitrary?

Those can be any name, does not matter, but the pins attached to those must be present in hal.
Here is an example for a XYYZ parallel port config for PlasmaC
