Fine but is that all that i need to add to my hal .
Somehow I suspect not
Please remember Andy that I am a novice here
My Hal was generated by initially by stepconfig and although I have progressively added a number of functions I have not needed to alter the spindle commands so i am floundering here !

Which output pin (if any) is connected to your reversing relay?
Is it safe to reverse with the spindle on?

Was planning for 14 or 16 unless you advise otherwise
Would not be safe to call for M4 if spindle running under M3 and Vice versa .
Was planning to call for a pause but if that can automated then all the better

I hope you find this use full.
I'm using a servo motor for my spindle as the original DC motor was failing.
I have a dual 5v relay board from Ebay for around £4 for the control switching of the spindle.
The servo drive requires:
- Spindle enable
- Analogue 0-10v for its speed control, therfore:
Spindle Enable (Relay)
setp parport.0.pin-16-out-invert 1
net spindle-on => parport.0.pin-16-out
Spindle Direction (Relay)
net spindle-cw => parport.0.pin-17-out
Pin 17 output is connected to a small 5v relay wired normally open in series to the Polarity Reversing Modual
When CW is required, then 5v relay energises the Polarity Modual and +10v swaps to -10v for example.

Not sure this fits my need s Ride
My pin 17 switches on the spindle and speed increase via the 0-10 v dc analogue output increases the speed .
I dont think I can change this to minus 10v .
My reversing relay simply reverses polarityat my DC motor which can be plus 170v to run forward and up to minus 170v to run backwards

If you absolutely must not reverse the motor when it is running then that can be achieved with HAL trickery, but it would require that there be a spindle encoder so that the system can know that the spindle is stopped or moving.
But, the logic shown by rider-83 should work for you anyway, in that a parport pin will be set high in reverse. What happens in the hardware past that point is up to you.

So the following is a c/p from my Hal
setp parport.0.pin-01-out-invert 1
net spindle-pwm => parport.0.pin-01-out
net xstep => parport.0.pin-02-out
setp parport.0.pin-02-out-reset 1
setp parport.0.pin-03-out-invert 1
net xdir => parport.0.pin-03-out
net zstep => parport.0.pin-06-out
setp parport.0.pin-06-out-reset 1
net zdir => parport.0.pin-07-out
net spindle-on => parport.0.pin-17-out
net spindle-cw => parport.0.pin-16-out
I seem to need this format for my spindle to start and for me to have speed control
I am looking for pin 16 to operate my reversing relay
i do not see this as different from yours rider-83 except I have transposed 16 and 17 unless I am missing something
I am not getting any error messages But my reversing relay is not being operated
Is there anything wrong with the above
setp parport.0.pin-01-out-invert 1
net spindle-pwm => parport.0.pin-01-out
net xstep => parport.0.pin-02-out
setp parport.0.pin-02-out-reset 1
setp parport.0.pin-03-out-invert 1
net xdir => parport.0.pin-03-out
net zstep => parport.0.pin-06-out
setp parport.0.pin-06-out-reset 1
net zdir => parport.0.pin-07-out

Try:
net spindle-ccw => parport.0.pin-16-out
net spindle-ccw => parport.0.pin-16-out
