	isBlinking = true;
	
// Character color attributes
if ((color & ScreenUPG.ScreenUPG.FgBlue) != 0)
	isForegroundBlue = true;
if ((color & ScreenUPG.ScreenUPG.BgYellow) != 0)

Get the presentation space at row 18, column 6 with length 10
ps = screen.getExtPS(18, 6, 10)
attribute = Mid$(ps, 2, 1)
color = Mid$(ps, 3, 1)
if ((attribute And screen.Blink) >< 0) then isBlink = True
if ((attribute And screen.Underscore) >< 0) then isUnderline = True
if ((attribute And screen.Reverse) >< 0) then isNegative = True
