Using‑data‑length‑vector
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.
