The program has doubled in size from 8 to 16 lines. In larger pro-
grams the space savings from usirrg subscripted variables will be even
more dramatic. .
TWO-DIMENSIONAL ARRAYS
Earlier in this chapter you experimented with one-dimensional arrays.
This type of array was visualized as a group of consecutive boxes within
memory each holding an element of the array. What would you expect
a two-dimensional array to look like?
First, a two-dimensional array would be written like this:
A(4,6)
r t!scRIPTS
ARRAY NAME
and could be represented as a two-dimensional grid within memory:
~
1
2
3
4
The subscripts could be thought of as representing the row and col-
umn within the table where the particular element of the array is stored.
