Absolute position of joint?

Is there a HAL pin, named or numbered parameter, or other source reporting the absolute machine position, e.g. position relative to home?

Commanded axis position in machine coordinates: halui.axis.L.pos-commanded
Feedback axis position in machine coordinates: halui.axis.L.pos-feedback
Commanded axis position in relative coordinates: halui.axis.L.pos-relative

(replace 'L' with axis name)
More info here: linuxcnc.org/docs/html/man/man1/halui.1.html

Is this what you need?

Thanks JPL. I think I should have slept before asking that question. I had an issue yesterday that I couldn't figure out - it looked like the halui.axis pin values were changing with G54. Now looking at it this morning, I see they aren't.
