re:re:g-code parsers

Les,

Stepster is a BASIC (powerbasic, a compiled basic) g code controller.
The parser is straight forward and fast. Not especially great code,
but a different approch than emc. The EMC parser does a phenomenal
amount of error checking. Remember that the EMC flavor of Gcode is
based on an old A/B dialect. Please 'write' for current standards.

Hope this helps.

How old is your book? You may want to separate your code modules such
that implementing a new 'flavor' is easy. The same way good software
keeps the UI text 'separate' so it can be written for different
countries' languages.

See notes above.
