Article: Q44236

Only one page (page 0) is supported in SCREEN mode 0 on a Hercules
adapter. To obtain two pages, Hercules graphics mode (SCREEN 3) should
be used.

The indicated documentation sources below incorrectly show two pages
(pages 0 and 1) available in SCREEN mode 0 (TEXT mode) on a Hercules
adapter. This is incorrect.

The information covering "Hercules Adapter Screen Modes" in the
following sources incorrectly states you can have 2 pages under SCREEN
mode 0 when using a Hercules video adapter:

1. The documentation error occurs in QB.EXE 4.50 QB Advisor online
   Help system under the HELP menu, SCREEN statement, Details section,
   Adapters and Displays ("HELP: SCREEN Statement Details - Adapters")

   This documentation error has been corrected in the Microsoft
   Advisor on-line Help system of the QBX.EXE environment supplied
   with Microsoft BASIC PDS versions 7.00 and 7.10 for MS-DOS.

2. This documentation error occurs on Page 327 of the "Microsoft
   QuickBASIC 4.5: BASIC Language Reference" manual.

   This documentation error has been corrected in the "Microsoft BASIC
   7.0: Language Reference" manual for BASIC PDS version 7.00 and 7.10.

3. This documentation error occurs in the QBX.EXE 7.00 and 7.10
   Microsoft Advisor online Help system under the HELP menu, PCOPY
   statement, Details section ("HELP: PCOPY Statement Details").

   This documentation error does not occur for PCOPY HELP in QB.EXE
   4.50.
