Q45906: No Extended ASCII in SCREEN 4 on Olivetti/AT&T 6300

Article: Q45906
Product(s): See article
Version(s): 4.00b 4.50
Operating System(s): MS-DOS
Keyword(s): ENDUSER | SR# S890606-97 | mspl13_basic
Last Modified: 22-JUN-1989

It has been reported that when using QuickBASIC Version 4.00b or 4.50,
characters in the extended ASCII character set (codes 128 to 255) are
not visible in SCREEN 4 on an AT&T 6300. However, the extended
characters are visible in SCREEN 0 (text mode).

This may be a hardware limitation. Microsoft is researching this
problem and will post new information as it becomes available.

Code Example
------------

The following code example displays blanks in SCREEN 4, but displays
the correct extended characters in SCREEN 0:

SCREEN 4     'works for SCREEN 0
FOR i%=128 TO 255
   PRINT CHR$(i%)
NEXT i%
