Thanks for your help guys
I kind of agree with way the comments are handled
It needs to not be machine readable
I had gcode that was uncomented
And had my machine attempt to do stuff
That thankfully was no real harm but the potential
Of having a machine move before it is homed
Could cause a problem along with cold extrusion
And a number of machine specific things that could go wrong
I too agree that pausing should be a simpler task
