1.1 Variables
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
Example:
Program code
DEF INT ARRAY[5,5]
ARRAY[0,0]=SET(1,2,3,4,5)
FELD[0,0]=SET(1,2, , ,5)
ARRAY[2,3]=SET(VARIABLE,4*5.6)
Further information (
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)

; Array definition
; Value assignment to the first 5 array
elements [0,0] - [0,4]
; Value assignment with gap to the first 5
array elements [0,0] - [0,4], array
elements[0,2] and [0,3] = 0
; Value assignment with variable and
expression starting at array index [2,3]:
[2,3] = VARIABLE
[2,4] = 4 * 5.6 = 22.4

elements [0] to [3] with value 3.5.
