CALCPOSI is for checking whether, starting from a defined starting point, the geometry
axes can traverse a defined path without violating the axis limits (software limits), working
area limitations, or protection zones. If the defined path cannot be traversed without
violating limits, the maximum permissible value is returned.

Explanation
AXNAME: Get axis identifier
Converts the input string to an axis identifier. An
alarm is generated if the input string does not
contain a valid axis identifier.
AXTOSPI: Convert axis to spindle
Converts an axis identifier into a spindle number.
An alarm is set if the transfer parameter does not
contain a valid axis identifier.
SPI: Convert spindle to axis
Converts a spindle number to an axis identifier. An
alarm is generated if the passed parameter does
not contain a valid spindle number.

Intersection: Calculation of
intersection
The intersection between two
contour elements is calculated.
The intersection coordinates
are return values. The error
status indicates whether an
intersection was found.
