HAL Newb, troubleshooting code that "Works-ish"

I'm having some trouble with coding some things that shouldn't be too hard I don't think but I'm just not seeing what the issue is.

It's supposed to turn the spindle on/off but I can't do it like I did mist because halui.spindle.is_on doesn't exist, so I'm getting "Hack-ey" on it, LOL.

This code "works", either using the line that is commented out at the end or with the commented last couple of lines in place. The first way doesn't check machine on so it throws an error about not being able to activate spindle.stop while machine is off. (Assuming that you try it with machine off.... machine on is fine.)

The second way properly ignores the request when the machine is off, but when I launch LinuxCNC it "Hangs" for 40+ seconds and spins it's wheels before I can activate the power button. Once the button becomes available it works fine.

HAL Guru's, please advise, I swear I am searching diligently for answers before asking!

halui.spindle.is-on (bit, out) - indicates spindle is on (either direction)

'Doh!

Well, that will do it, LOL.

I was using wiki.linuxcnc.org/cgi-bin/wiki.pl?Halui as my reference, which I guess is incomplete.

On the plus side.... I now have a glimmer of hope that I can get my head around this HAL thing in general, LOL.

Thanks for pointing me in the right direction! Sometimes figuring out which info is the most current is half the battle.
