Example of a granular pyramid form,|
aka 'square vector orbit' CCW path
As each motion is completed,
an inverse of that motion is placed on a 'reverse path stack'.
This long winded list of the code shows a path aborted in N190,
and an 'all clear' signal in N120
break out the quadrule paper and pencils and watch it...

so, if the program was aborted in the midst of line 190,
the 'trick' is to run the reverse program that was auto built.
the example shows an 'all clear ( ok to proceed ) occur in N120
this cause the return program to end,
and we'll want to continue, with the original program, but beginning at N190
(need to automate seeting the 'run mark' and knowing where to set it )
the above idea retraces the path, and is suitable for wire edm
in wire edm even arcs could be automaticly translated to lots of linear moves (as seg q would)
