This may be the best solution, as some people are very adamant that the way
EMC works now is "right". I've used the multiple coord systems when I had
multiple features to be made with the same program at known offsets from the
first one.

I have never used the % in EMC (I did use it on the A-B 7320). It is an
ARCHAIC
hack, so the control could tell whether the paper tape was in ASCII or
EIA punch
code format! I always used to use M02, but to save my G92 offsets, I
used M01.
But, I should probably get used to the G10 L2 Pn
