Total lines in a GCode file

Try the scale component (set gain to 0.01) to convert 0..100 to 0..1:
linuxcnc.org/docs/html/man/man9/scale.9.html

In case anyone else needs to work with HAL_HBar and HAL_VBar components in Glade, it turns out that I didn't have my hal file configured correctly for the HBar. Within Glade, there is a description the zone limits for color changes is based on 0.0 - 1.0 which is a fractional percentage of the MAX/MIN limits, not what is required for input. Hence, what ever the MAX?MIN limits are set to, zones are based on the fractional percentage of that range.

I had to remove the SCALE component and just net gmoccapy.program.progress directly to the GLADE HAL_HBar component for everything to work as expected.

Thank for all you help.

in master branch 2.10, the currently executing line number can be found on this pin
motion.interp.line-number
If you get the number of lines as gmoccappy does you can calculate the percent processed in real time
