When USING-data-count is not zero, USING-data-length-vector is a four byte pointer to a vector of four- byte lengths. The lengths specify the amount of data addressed by corresponding pointers in the USING-data-pointer-vector when Variable-length-request is not specified. When Variable-length-request is specified, USING-data-length-vector is ignored. The number of entries in the vector is given by USING-data-count.
USING-data-length-vector exists only when DBCHINI had been called for a DBCAREA with Total-length set to at least 640 (that is, the returned DBCAREA Level value is at least 1). For a smaller DBCAREA, USING-data-length-vector is ignored.
