Initialization during definition
● All or the optionally specified number of array elements are initialized with the specified
value (constant).
● Variables of the FRAME data type cannot be initialized.
Example:
Program code Comments
DEF REAL varName[10]=REP(3.5,4) ; Initialize array definition and array
elements [0] to [3] with value 3.5.
Value assignment in program execution
In the case of value assignment in program execution, the rules described above for
definition apply. The following options are also supported:
● Expressions are also permitted as elements in the value list.
● Value assignment starts with the programmed array index. Values can be assigned
selectively to subarrays.
Examples:
Program code Comments
DEF REAL varName[10] ; Array definition
varName[5]=REP(4.5,3) ; Array elements [5] to [7] = 4.5
R10=REP(2.4,3) ; R-parameters R10 to R12 = 2.4
DEF FRAME FRM[10] ; Array definition
FRM[5] = REP(CTRANS (X,5)) ; Array elements [5] to [9] = CTRANS(X,5)

Value assignments to axial machine data
In principle axial machine data have an array index of the
AXIS data type. In the case of
value assignments to an axial item of machine data using
SET or REP, this array index is
ignored or not processed.
Example: Value assignment to machine data MD36200 $MA_AX_VELO_LIMIT
$MA_AX_VELO_LIMIT[1,AX1]=SET(1.1, 2.2, 3.3)
Is equivalent to:
$MA_AX_VELO_LIMIT[1,AX1] = 1.1
$MA_AX_VELO_LIMIT[2,AX1] = 2.2
$MA_AX_VELO_LIMIT[3,AX1] = 3.3
