Usage Notes
The size of the input area can be modified any time during a session and changes immediately whenever another SET INPUTAREA SIZE command is entered. The minimum allowable size for the input area is one line. When modifying the input area size, allow for at least ten lines in the display area. Ten lines is the minimum number required to display the result of one selected row in format mode.
A selection result in the display area at the time the command is entered remains formatted according to its original display area size until the user rewinds its spool file by executing a BACKWARD * command.
