Are nested subroutines possible?

Can anyone help with the syntax for a nested subroutine? Or to rephrase how can you call a sub from another subroutine?
I've written a couple of linux subroutines using the repeat function, so I get the basics, but it doesn't appear that you can call a sub from within another sub?

here is a Fanuc example, distilled to the basics that works but I can't wrap my head around making this work in linux syntax.

If anyone could provide a simple example like this I'd appreciate it!
Thx.

If the subroutines are specific for this machining, you could put everything in one file.Then this example must be saved as (yourfile).ngc. Otherwise save the subroutines and the main, calling the subroutine as single file. You could set the repetitions from the main calling file, so the subroutines stay variable.


o1234 sub
o111 repeat [#1]

;nccode

o5678 call [#2]
o111 endrepeat
o1234 endsub

o5678 sub
o112 repeat [#1]

;nccode

o112 endrepeat
o5678 endsub

; M A I N
o1234 call [17][12]

M2

Are you wanting to use the Fanuc-style subs or would LinuxCNC-style subs be acceptable?

Have you tried LinuxCNC-style? ( O100 SUB / O100 ENDSUB / O100 CALL )

Thank you. That was just what I needed. 'Repeat' was a big help and just the order of how things are done.

I'm moving from Mach3 to Linux(pathpilot) and none of my current programs work. so, I'm learning all of the new syntax and converting the programs but there are lots of differences.

Something that you didn't mention is what version of LinuxCNC you are using.

The M98 / M99 subroutine format was only added to the LinuxCNC development branch very recently (for compatibility with some other controls). Is that the version you are using?
