Mechanism‑data‑len
If additional data is required by the specified Mechanism‑name, Mechanism‑data‑length specifies the length, in bytes, of the area addressed by Logon‑mechanism‑data‑pointer. If a Mechanism‑name is not specified, the value will be ignored.
Mechanism‑data‑len 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, Mechanism‑data‑len is ignored.
Note: Logon mechanisms are currently not supported for a mainframe‑connected system.

This field is ignored if Variable‑length‑request is set to Y, in which case Logon‑mechanism‑data‑pointer addresses a two‑byte area containing the length of the data, followed by the data itself.
