Apparently has been modified, see snip below from page 812 of the current
docs, I finally found it with zero help from the index.

And on page 812, I find this example:
value = hal.get_value("iocontrol.0.emc-enable-in")
So I'll use that syntax just for S&G.
Then I noted the dblquotes around the hal-pinname, but now it is an unk
where a unary could be. Gonna take more figuring I think.
Thanks again.
