Example
Data item is stored in packed decimal format in COMP-3. Packed-decimal format means that each byte of storage (except for the low order byte) can contain two decimal numbers. The low-order byte contains one digit in the leftmost portion and the sign (positive or negative) in the rightmost portion.
"Zoned decimal format" in the image below is the default storage for a number in COBOL.
01 WS-NUM PIC 9(5) USAGE IS COMP-3 VALUE 21544.
Computational storage is frequently used to reduce the size of a file.
