Re: [CAD_CAM_EDM_DRO] Re: G-code user variables; convention?

Alan,

for a roll your own interpreter the #NamedVariables would be fine ,but
the programs would not be portable to a diffrent machine,not very
many are anyway of course ;-)
they would make programs more readable
you could also keep the usual numbered variables and add a
NAME field to the variable table ie.

#0100 [ALIAS #MyVariable]; (sets the name field)
#MyVariable = 2.54;

or even

#define #0100 #MyVariable

and pass the program thru a preprocesor step before running it
(could also check for out of range numbers,bad calls,etc)

Ps Okuma and one or two others use 'V' for variables as well
most mills I've seen to use the'#' sign
