'These routines will input a line of text of up 32K, within the bounds
' of the window specified.  If more text is inputted than there is room,
' the text scrolls.  Insert, delete, home and end all perform expected
' functions.  Color is not supported, but could be added without difficulty.
'A quirk: Although the text scrolls at 'right', an additional space is
' required for the cursor, and this space -will- overwrite anything at
' that location.  So count on allowing at least one blank space beyond
' 'right'.
'This routine works without speed problems on my 386DX/40.. but I have
' not tested on anything slower.  If anybody sees a problem, please let
' me know!
