Linux is basically useless to me unless I run EMC and I intend not to go
thru with it what others seem to have to go thru. It is totally
inconceivable to me that it will either lose offset values or sum them up
in some arcane way when you use another ordinary control function! That is
not only ineffective and counterproductive, it's well past damned
dangerous. My program writes them to a file on disc and they can only be
altered by the operator overwriting them or editing the file. Thats the way
all other sytems seem to work, and I don't think I'm missing anything.

The advantage to me is entirely theoretical.

I'm doing just fine with my own stuff which having written myself I can't
help but be happy with.

There can never be any real and lasting consistency in open source code,
unless you have a deity to manage the individual programmers.

I will never have a problem in implementing the way any flavor of Gcode
runs, because I wrote the interpretor I'm using. However, I haven't had to
run Gcode yet anyway, as my system also uses an alternative fully
implemented command set.

If you have an answer to the question I posed, I'd sure like to hear it.
