Value assignment in program execution
In the case of value assignment in program execution, the rules described above for the
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
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))
