Support commands establish the FastExport sessions with the database and define the operational support environment for the FastExport utility. Established support environment options remain in effect until another support command changes them. Support commands do not specify a FastExport task.

| ENDIF (see IF, ELSE, and ENDIF) | Delimits the group of FastExport commands that were subject to previous IF or ELSE conditions |
| IF (see IF, ELSE, and ENDIF) | Introduces a conditional expression whose value initiates execution of subsequent commands |
| LOGOFF | Disconnects all active sessions and terminates FastExport |
| LOGON | Specifies the LOGON string to be used in connecting all sessions established by FastExport |
| LOGTABLE | Specifies a restart log table for the FastExport checkpoint information |
