Initialization of array variables with SET, REP

Function
Array variables can be initialized or described with particular values in synchronized actions.
Programming
DO ARRAY[n,m]=SET(value1, value2, ...)
or
DO ARRAY[n,m] = REP(value)
Initialization starts at the programmed array indexes. For 2D arrays, the second index is
incremented first. This is not done with axis indices.
Value assignments of array variables
Only variables that can be described in synchronized actions are possible. Machine data
cannot therefore be initialized. Axis variables cannot be specified using the NO_AXIS value.

SET(value list)
The array is described from the programmed array indices onwards using the SET
parameters. As many array elements are assigned as values are programmed. If more
values than exist in the remaining array elements are programmed, a system alarm is
triggered.
REP(value)
The array is described from the programmed array indices to the end of the array and
repeated using the REPparameters.
Example
WHEN TRUE DO SYG_IS[0]=REP(0)
WHEN TRUE DO SYG_IS[1]=SET(3,4,5)
Result:
SYG_IS[0]=0
SYG_IS[1]=3
SYG_IS[2]=4
SYG_IS[3]=5
SYG_IS[4]=0
