/* Interpreter global arrays for g_codes and m_codes. The nth entry
in each array is the modal group number corresponding to the nth
code. Entries which are -1 represent illegal codes. Remember g_codes
in this interpreter are multiplied by 10.

The modal g groups and group numbers defined in [NCMS, pages 71 - 73]
(see also [Fanuc, pages 43 - 45]) are used here, except the canned
cycles (g80 - g89), which comprise modal g group 9 in [Fanuc], are
treated here as being in the same modal group (group 1) with the
straight moves and arcs (g0, g1, g2,g3).  [Fanuc, page 45] says only
one g_code from any one group may appear on a line, and we are
following that rule. The straight_probe move, g38.2, is in group 1; it
is not defined in [NCMS].

Some g_codes are non-modal (g4, g10, g28, g30, g53, g92, g92.1, g92.2,
and g92.3 here - many more in [NCMS]). [Fanuc] and [NCMS] put all
these in the same group 0, so we do also. Logically, there are two
subgroups, those which require coordinate values (g10, g28, g30, and
g92) and those which do not (g4, g53, g92.1, g92.2, and g92.3).
The subgroups are identified by itemization when necessary.

Those in group 0 which require coordinate values may not be on the
same line as those in group 1 (except g80) because they would be
competing for the coordinate values. Others in group 0 may be used on
the same line as those in group 1.

A total of 52 G-codes are implemented.

The groups are:
group  0 = {g4,g10,g28,g30,g53,g92,g92.1,g92.2,g92.3} - NON-MODAL
            dwell, setup, return to ref1, return to ref2,
            motion in machine coordinates, set and unset axis offsets
group  1 = {g0,g1,g2,g3,g33,g33.1,g38.2,g38.3,g38.4,g38.5,g73,g76,g80,g81,g82,g83,g84,g85,g86,g87,g88,g89} - motion
group  2 = {g17,g17.1,g18,g18.1,g19,g19.1}   - plane selection
group  3 = {g90,g91}       - distance mode
group  4 = {g90.1,g91.1}   - arc IJK distance mode
group  5 = {g93,g94,g95}   - feed rate mode
group  6 = {g20,g21}       - units
group  7 = {g40,g41,g42}   - cutter diameter compensation
group  8 = {g43,g49}       - tool length offset
group 10 = {g98,g99}       - return mode in canned cycles
group 12 = {g54,g55,g56,g57,g58,g59,g59.1,g59.2,g59.3} - coordinate system
group 13 = {g61,g61.1,g64} - control mode (path following)
group 14 = {g96,g97}       - spindle speed mode
group 15 = {G07,G08}       - lathe diameter mode

Modal groups and modal group numbers for M codes are not described in

extension of the language for pallet shuttle and stop. This version has
no codes related to axis clamping.

The groups are:

group 5 = {m62,m63,m64,m65,  - turn I/O point on/off

   Each read function is placed in the array according to the ASCII character it
   corresponds to. Whilst a switch statement could have been used in read_one_item,
   using an array of function pointers allows a new read_foo to be added quickly
   in this one table.
