The following table is a list of types. Many of these Types can be used together (example: PACKED DECIMAL).
| Type | Description |
|---|---|
| ASCII NUMERIC | Numeric characters in ASCII. |
| BOOLEAN | BOOLEAN may also be qualified as INTEGER. They are treated as right justified binary integers; however, fields with the value of zero are considered to be equal to FALSE, while fields with a non-zero value are considered to be TRUE. |
| BINARY | Binary data type. |
| INTEGER |
INTEGER types may be signed or unsigned. They are treated as right justified binary integers of the length specified in the LENGTH statement. Integers may also be qualified as BOOLEAN. Note: The maximum length of an INTEGER type is 4.
|
| PACKED | PACKED types can be signed or unsigned. Packed decimal digits of the length are specified in the LENGTH statement in bytes. They are treated as right-justified. Since packed decimals are stored two digits to a byte, the total number of digits is twice the length for UNSIGNED PACKED and twice the length minus 1 for signed PACKED. For signed values the right-most nibble holds the sign value. |
| ZONED DECIMAL | The ZONED DECIMAL type is treated as EBCDIC NUMERIC characters with the least significant byte divided into a numeric digit and a sign. The sign occupies the least significant nibble of the byte and follows the conventions for PACKED decimal signs. |
