Length adjunct

GDDM V3R2 Base Application Programming Reference
SC33-0868-02

The length adjunct is a two-byte field that can contain values in the range 0 through the length of the field. It indicates the length of the data in the data field. GDDM treats a value greater than the field length as if it were equal to the field length.

When a field is displayed, GDDM pads the data with nulls, from the length specified in the length adjunct, to the length of the display field.

After the operator modifies a field, the length adjunct specifies the number of bytes of data placed in this field by the input operation.

If right-hand justification has been specified for the field during map definition, the length adjunct is set on input to the length of the field in the application data structure. If left-hand justification has been specified, the length adjunct is set to the number of characters in the field up to the first padding character.
