QuickBasic WIDTH Command Resets Default Values for PALETTE (41040)

This article was previously published under Q41040

SYMPTOMS

Any switch of WIDTH causes the PALETTE values to be reset to their default values. In the example code below, the circle is always drawn in the color of the default value for PALETTEs 1 to 15. It should always be drawn in the color corresponding to 15948 (63 * 256). This is true of all SCREENs that allow multiple page lengths.

STATUS

Microsoft has confirmed this to be a bug in Version 4.00, 4.00b, and 4.50 and in Microsoft Basic Compiler Versions 6.00 and 6.00b for MS-DOS and OS/2 (buglist6.00, buglist6.00b). We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

The following code will reproduce the problem:

CLS
SCREEN 12
i=0
FOR k = 1 TO 15
   PALETTE k, 63 * 256
   i = 30-i
   WIDTH 80, 30 + i
   CIRCLE (100, 100), 80, 5
   PAINT (100, 100), k, 5
   LOCATE 20, 1: PRINT i, k; : INPUT a$
