Hello everyone:
LinuxCNC G code has no function to jump to a specific line.
such as G25 of some CNC manufacturers.
N10 G01 X10 F10
N20 G01 Y10 F20
N30 G25 N10
N40 G01 Z10 F20
Jump to N10 when executing to N30
How to realize the function of jumping to the specified line?
Need everyone's help, thanks！

Why can't you use a loop instead?

If you just want an endless loop
linuxcnc.org/docs/stable/html/gcode/o-code.html
(but note that the G-code preview tends to get stuck in inifinite loops)
O100 WHILE [1]
do stuff
O100 ENDWHILElinuxcnc.org/docs/stable/html/gcode/o-code.html

Hi, thanks for your suggestion, I will try the loop way.
I will improve the Gcode content. The usage scenarios are mainly used for conditional jumps.
For example G code:
N10 G01 X10 F10
N20 G01 Y10 F20
N30 if [#1 ET 5 ] G25 L100 endif
N40 G01 Z10 F20
...
N100 G01 U 10 F20
...
M2
When the program satisfies this N30 conditional program, it will transfer its designated block N100.

In LinuxCNC (and anything else using NIST-standard G-code) you do this with:
N10 G01 X10 F10
N20 G01 Y10 F20
O100 if [#1 NE 5 ]
N40 G01 Z10 F20
...
O100 ENDIF
N100 G01 U 10 F20
...
