As can be seen, the second displayed value (which should be 2) in A[2] is incorrect. This problem has
occurred because memory A[2] is the same as memory C.
A B
A[1]
The content of memory C (A[2]) is decreased from 5 to 0 in steps of 1.
Therefore, the content of memory A[2] is displayed as 0.
4.8.3 Application of the array-type memories
It is sometimes required to treat two different types of data as a single group. In this case, memories for
data processing and those for data storage should be kept separate.
Example: store data x and y in memories. When an x value is input, the corresponding y value is dis-
played. There will be a total of pieces of data.
Example program 1
Memory A is used as the data control memory, and memory B is used for temporary storage of the x data.
The x data are stored in memories C[1] (memory D) through C[15] (memory R), and the y data are stored
in memories C[16] (memory S) through C[30] (memory Z(7)).

In this program, memories are used as follows:
x date: C[1]
D
C[9]
L
y date: C[16]
S
Z: C[24]

Example program 2: The same memories are used as in Example 1, but two types of memory names are
used and the x and y data kept separate
