Which is why, when I'm working on a hal file, a copy of that section

see me asking questions too. So don't think you are too far afield
when adding something to your machine and have to ask for a howto.
Its the nature of the beast. I am, by the week, discovering some of
the things linuxcnc can do that I hadn't a clue it could do, yet
properly programmed, it just works. Its humbling to me, for sure.
Andy touched on something in a previous msg in this thread, an item
I may have been tempted to suggest, and that is the order of signal
names, argument #1 to a net statement. To explain it from my view:
net netname src target
That establishes the netname as a copy of the src signal, and the
src of the signal, which needs to be the first encountered when
reading in the .hal file.
>From that point on, the netname is re-usable with this syntax:
net netname target [target] [target] etc, etc.
This will then distribute the src to all the named targets, and if
you run out of line room to hit all the targets, then another:
net netname target target target just expands the number of targets.
It can get confusing when there is 500+ LOC between the statements,
but hal doesn't care.
Oh yeah, I have a copy of the doccy's open too, along with the man
page for that particular thing I'm trying to implement. It's kinda
like recursion though. You don't understand recursion unless you
understand recursion. ;-)

I've heard that someplace before Mark. :) But you'll get it.
Recursion was a terribly interesting concept when I was taking
programming classes for my comp sci degree. Had a lot of fun with it
once I understood how to use it. We all had t shirts made up with that
saying on it. ;-)
