Usage Notes
When the INPUT command is entered, the display and input areas are cleared and the cursor moves to the beginning of the display area. The display area then becomes the edit area where statements can be entered. Acceptable commands from the input area or through PF keys are limited to ITEQ edit control commands and the SHOW, LOGOFF, and QUIT commands. ITEQ ignores any other command.
If the CLEAR INPUT command is entered before a statement i completed, the display area is cleared and reset to output mode.
The cursor is positioned at the beginning of the input area.
