CNC12 Acorn Pro v4.12: Is the variable that holds the "Z REF" value related to the Tool Offset Library available to read? If so, what # is it? Image attached but from CNC12 Mill Emulator v4.14 on my non-shop computer. I've done a lot of digging but I'm not finding it. Thanks.

It's system variable 24103. That system variable is associated with the Z Reference position with respect to Machine Coordinates. The value that is displayed when you go into the Tool Offset library is that position but with respect to the Work Coordinate System that you are in. The reason I am mentioning that is because I don't know exactly what you are looking to use that system variable for but if you just need to know the physical location of the Z Reference, then you just need to look at the value of 24103. If you are trying to find the value that is shown in the Tool Offset library, then you will need to do some math in order to display that position with respect to the current Work Coordinate System.
