Additional functions

14.1 Axis functions (AXNAME, AX, SPI, AXTOSPI, ISAXIS, AXSTRING,
14.1 MODAXVAL)
Function
AXNAME is used e.g. to generate cycles that are generally valid, if the names of the axes are
not known.
AX is used to indirectly program geometry and synchronous axes. The axis identifier is saved
in a type AXIS variable or is supplied from a command such as AXNAME or SPI.
SPI is used if axis functions are programmed for a spindle, e.g. a synchronous spindle.
AXTOSPI is used to convert an axis identifier into a spindle index (inverse function to SPI).
AXSTRING is used to convert an axis identifier (data type AXIS) into a string (inverse function
to AXNAME).
ISAXIS is used in universal cycles in order to ensure that a specific geometry axis exists
and thus that any following $P_AXNX call is not aborted with an error message.
This MODAXVAL is used in order to determine the modulo position for modulo rotary axes.
