re:Re: suggested improvement for EMC

Ian,

It is usually easy to(programming perspective, here) "back up a few
lines", BUT...

With Gcode, MANY things are modal and will have been set by previous
lines/blocks in the gcode. Any re-start from Nxxxx (previous line
number) NEEDS to either "recall" these modal states, or; "re-run"
through the program, quickly setting such modal flags/variables so
that when the line requested is run, it will run as expected!

Hope this helps.
