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)
