The JUSTIFIED_RIGHT field attribute truncates or fills a TEXT or UNSPECIFIED field from the left instead of from the right.
1 – Usage Notes
o Only VAX COBOL supports the JUSTIFIED RIGHT clause. Other language processors ignore it. o Use this clause only on fields whose data type is TEXT or UNSPECIFIED. 1 MISSING_VALUE The MISSING_VALUE field attribute clause specifies a value to indicate that a field has never been assigned a meaningful value.
2 – Parameters
fixed-point-number quoted-string The VAX DATATRIEVE missing value.
3 – Syntax Rules
o The quoted string or fixed point number must be a valid VAX DATATRIEVE expression for the field. The CDDL compiler does not check for correct syntax. o You can use 8-bit characters in CDDL quoted strings.
4 – Usage Notes
o Only VAX DATATRIEVE supports the MISSING_VALUE clause. Other language processors ignore it. o VAX DATATRIEVE treats a field containing a MISSING_VALUE as a special case; for example, VAX DATATRIEVE ignores fields containing a MISSING_VALUE when it performs statistical operations.
5 – Example
The following example assigns a missing value of 0 to the field PRICE. A PRICE of 0 indicates to VAX DATATRIEVE that the value for PRICE is missing; VAX DATATRIEVE ignores records with PRICE equal to 0 when it performs operations involving the PRICE field. PRICE DATATYPE IS UNSIGNED NUMERIC SIZE IS 8 DIGITS 2 FRACTIONS MISSING_VALUE FOR DATATRIEVE IS 0.
