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

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%)
