In graphics mode, the number of the color returned by the SCREEN
function will always have a value of 0 (zero).

This information applies to Microsoft QuickBASIC Versions 1.00, 1.01,
1.02, 2.00, 2.01, 3.00, 4.00, 4.00b, and 4.50 for MS-DOS and to
Microsoft BASIC Compiler Versions 6.00, 6.00b, and 7.00 for MS-DOS and
MS OS/2.

The SCREEN function has the following syntax:

   SCREEN (row,column[,colorflag])

When colorflag is nonzero, SCREEN returns the number of the color at
the location specified by row and column -- but only in text mode.

When colorflag is zero or absent, the ASCII code of the character at
the specified location is returned as an integer in both graphics and
text modes.
