BASIC's SCREEN 4 is designed for the Olivetti/AT&T high-resolution
screen mode (640 x 400). This screen mode allows you to run programs
that utilize the special screen mode available on the Olivetti PC,
models M24, M28, M240, M280, and M380, and the AT&T PC 6300 Personal
Computer series.

This information applies to Microsoft QuickBASIC Versions 4.00b and
4.50, Microsoft BASIC Compiler Version 6.00b for MS-DOS and MS OS/2,

If you have one of the computers mentioned above, you can utilize the
640 x 400 resolution screen mode by using SCREEN 4. The computers
listed above are the only computers with which this mode was tested;
therefore, Microsoft cannot guarantee that the mode works correctly on
