RESTORE STATEMENT
You can at any time send the pointer back to the beginning of the
numeric column by executing a RESTORE statement. Here is an example
of the use of RESTORE.
10 DATA 10, 20, 30, 40, 50, 60, 70, 80, 90, 100

VIC BASIC normally assumes that a variable has a single dimension,
with index values of 0 through 10. This generates an 1 I-element array.
If
you
want a single dimension with more or less than 11 elements, then you must
include the array variable in a dimension (DIM) statement. You also must
include the array in a dimension statement if it has two or more dimensions,
no matter what number of elements the array has. The following example
provides dimensions for one-dimension array variables MP$, FV$, and
DP$. We used these variables in our earlier discussion of arrays.
DIM MPS(5),FV'(3),DP'(2)
