Initialization during definition
● All or the optionally specified number of array elements are initialized with the specified
● Variables of the FRAME data type cannot be initialized.
Example:
Program code
DEF REAL varName[10]=REP(3.5,4)
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
Examples:
Program code
DEF REAL varName[10]
varName[5]=REP(4.5,3)
R10=REP(2.4,3)
DEF FRAME FRM[10]
FRM[5] = REP(CTRANS (X,5))

Value assignments to axial machine data
In principle axial machine data have an array index of the
value assignments to an axial item of machine data using

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
