Before a call to DBCHCL for the Connect function, applications set Varying-length-request either to Y or N, with the following results:
| When Varying-length-request is set to... | Then... |
|---|---|
| Y | the Logon-length field is ignored and the Logon-pointer must point to the two-byte area containing the length of the logon string, which is followed by the actual logon string. |
| N | the application must supply the length information separately from the logon string, in Logon-length. |
For more information, see Varying-length-request.
