Session‑desc‑length
Session‑desc‑length is a four-byte field: when the Variable‑length‑request option is “N” it contains the number of bytes addressed by the Session‑desc‑pointer field; when the Variable‑length‑request option is “Y”, Session‑desc‑length is ignored.
Use of Session‑desc requires a Connect‑type setting of “C”.
Session‑desc‑length 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, Session‑desc‑length is ignored.
