This article explains why the UP, DOWN, PGUP, and PGDN cursor keys
produce a beep when editing what is typed in response to the INPUT or
LINE INPUT statement at run time.
The input editor used by INPUT and LINE INPUT is a line editor only.
This means you can move and edit only horizontally, such as with the
LEFT and RIGHT ARROW cursor-control keys and the BACKSPACE key.
Attempts to use the UP, DOWN, PGUP, and PGDN cursor keys produce a
beep.
This information applies to Microsoft QuickBASIC 2.00 2.01 3.00 4.00
4.00B and 4.50, to Microsoft BASIC Compiler 6.00 and 6.00B, and to
Microsoft BASIC PDS Version 7.00 for MS-DOS and MS OS/2.
