The manpage is jogaxisget.9. and they look very close to identical, but
an ls -l shows:
-rw-r--r-- 1 pi pi 1321 Oct 2 05:38 jogaxisget.text
-rw-r--r-- 1 pi pi 1580 Oct 1 17:00 jogaxisget.txt
either one will do. even for copy/paste as hal treats tabs the same as
spaces and reads of past looking for the text.
Thank you everybody, problem solved. Now to figure out what to hook it up
to in a 700+ l.o.c. file containing at least 5000 signal names.
TL;DR unless interested in cnc machinery
The hookup syntax is :
net netname <input-signal >output-1 [output-2] etc etc
and there is not an example line to show how its hooked up to achieve the
desired logic outputs in the manpage. Only the invocation lines are
given.
This is what I wanted:

JOGAXISGET(9)
The idea is to keep a gui's radio buttons up to date with what the
machine is doing, when signals external to the gui ae used to move the
machine, in this case a pair of encoder dials that function like the
hand cranks on a manual machine when it has been converted to cnc
control. With a per click distance ranging from .0001 inches to 20
thousanths per click. All this extra is unique to my machine, I wrote
it.
The dials I have added are very handy when one is finding the positions
to start a machining operation from, but at present, applying a
touch-off to establish that point does not update the gui's radio
buttons, so you find a point, and blindly apply the touch-off, only to
discover the touch-off has been applied to the wrong axis because the
radio buttons have not been updated by moving the machine with the
dials. This logic module is designed to act the same as a keyboard jog,
which does update the gui's radio buttons. But its up to me to find the
right signals to tie together to adhieve that, as they are mutually
exclusive, only one can be TRUE at a time, the most recent. For a lathe,
which only has 2 axis's only X and Z pins will be used, but for a mill
at least 3 need to be "hooked" up. But both of my mills have 4 asises,
and could have as many as 9. And since this module was written
the "axis" and "joints" have been divorced for increased versatility, so
the the subnames on the 2nd line are now duff and the new names will
have to be found by experimentation. And I'm the first to use this
module, so I get to write the translation rules.
Since N=69! is the largest that a ti calculator can handle, fun it won't
be, cuz N is well north of 1000 in this case.
Cheers, Gene Heskett.
