Read and write NC machine and NC setting data

Function
It is also possible to read and write NC machine / setting data of synchronized actions. When
reading and writing machine data array elements, an index can be left out during
programming. If this happens in the part program, all of the array's elements are described
with the value when reading the first array element and when writing.
In synchronized actions, only the first element is read or written in such cases.
Definition
MD, SD with
$: Read the value at the interpretation time of the synchronized actions
$$: Read the value in the main run
Read MD and SD values at the preprocessing time
They are addressed from within the synchronized action using the $ characters and
evaluated by the preprocessing time.
ID=2 WHENEVER $AA_IM[z]<$SA_OSCILL_REVERSE_POS2[Z]-6 DO $AA_OVR[X]=0
;Here, reversal range 2, assumed to remain static during operation, is addressed for
oscillation.
Read MD and SD values at the main run time
They are addressed from within the synchronized action using the $ characters and
evaluated by the main run time.
ID=1 WHENEVER $AA_IM[z]<$$SA_OSCILL_REVERSE_POS2[Z]-6 DO $AA_OVR[X]=0
;It is assumed here that the reverse position can be modified by a command during
the machining
