option base
Syntax:
OPTION BASE
(0 | 1)
Description: Statement. Declares the default subscript for the first array element.
Remarks:
The
OPTION BASE
declaration can be made only once; before any variables have been declared. If
the declaration is not made the first element in an array has subscript 0 by default.
Examples: > 10 OPTION BASE 1
> 20 DIM A(2)
> 30 FOR I = 0 TO 1
> 40 A(I) = I
> 50 NEXT I
> 60 FOR I = 0 TO 1
> 70 PRINT A(I)
> 80 NEXT I
> RUN
