Just to put Paul Carapetis at ease: The display of file/data/program icons on the screen of the Mac is essentially a function of the Mac operating system (or desktop). The appearance of an icon does not imply that the associated file has executable facilities for display of such an icon, in the same way that an MS-DOS file does not have code to display its filename.ext when you enter a DIR command. However, should an icon alter its appearance then this can only be attributed to executable code which may be contained anywhere on the system, not necessarily within the associated file. This follows from the fact that the icon is essentially no more than a pixel map. Mac users will know that the map contains small, background and highlighted descriptions. You can even edit them using ResEdit or similar tools. I don't recommend it. Rotan Hanrahan. Researcher, Dept Comp Sci UCD Ireland (HANRAH88@IRLEARN)
