Help! I'm an idiot

Yes, I am, I haven't upgraded LCNC for a while so I thought it was time, so I upgraded to the latest while doing others tasks and lost everything and couldn't find my backup from a couple of years ago, Doh!.Anyway it's mostly all back again just a few tweaks and the laser software to go.Finally my problem is with the xhc-hb04 pendant, it is working except for  the probe-z button which call a subroutine from a mdi-command and the subroutine is not being found. (seeking o-word<o100>;)I cannot find what I have missed, the PROGRAM-PREFIX is correct, the file is in the PATH and I added SUBROUTINE-PATH for good measure.
(please remove .txt from o100 file)
Can I get help please.
Eric

In the subroutine it is named o100, but the o-word file must be saved as 100.ngc

Thanks for the responses, I double checked that the subroutine was executable, and added .ngc but I still have the same error of not finding the file.
I may revert back to the previous edition I had to see if that makes a difference.
cheers

I reinstalled the previous version (2.8.2) but got the same result so the problem is in my setup.
Reinstalled 2.9.2 and will continue to look, any other suggestions welcome
Eric

From the first post,  seeking o-word<o100>   ,seems the file is saved as o100.ngc, which is wrong, as i mentioned before. it should be just 100.ngc

Yes, thanks that was it, I had better go and reread the manual, Now to solve the other faults it is throwing up
thanks again
Eric

Just on another issue , the max-velocity and max acceleration seems to be fine when using the mouse to move the axis on the AXIS screen but using the pendant the velocity seems too much, as the steppers seem to whine a little on stopping.
Not sure if I explained that correctly.
any thoughts anyone... I'm no expert at any of this.
