Predefined procedures

The call of a predefined procedure triggers the execution of a predefined NC function. A
predefined procedure does not supply a return value in contrast to a predefined function.
Coordinate system

As a general rule, geometry or special axis identifiers can also be used instead of the machine axis identifier, as long as the
)
reference is unambiguous.
