Changing program settings

Function
All parameters defined in the program header, with the exception of the dimension unit, can
be changed at any location in the program.
The settings in the program header are modal, i.e. they remain active until they are changed.
Define a new blank, e.g. in the machining step program, if you want to change the visible
section during simulation.
This is useful for the work offset, coordinate transformation, cylinder peripheral surface
transformation and swiveling functions. First program the functions listed above and then
define a new blank.
