There is probably something obvious I am missing but here goes my question.

How do I set up public constants to refer to 1280n pins (ZX-1280n development board) via logical A-L port and bit designations that I can use with GetPin and PutPin?

I have been looking for the answer to this all morning in the documentation.

On all ZX devices, you may refer to a pin by its physical pin number or by its port.bit designation. For example, on the ZX-1280n if you want to refer to bit 3 of port L you can use either 38 or L.3.

As for defining constants to refer to the pins, just define a Byte constant and specify its value as described above.
Code:
Public Const lcdPin as Byte = L.3

Yes, it figures that I would figure it out just minutes after I post my question!

My problem was that I was trying to implement a type conversion from a string that wasn't required.

Now I am off to discover my next challenge!

The unknown unknowns are inscrutable indeed, as compared to the known unknowns, that is.

Didn't Rumsfeld say something about this? Maybe the most intelligent thing he was recorded saying.
