Thanks for all the interesting responses. From what I have gathered, it appears that there is a consensus that mixed case has better legibility than all upper case. However, I am still tracking down references to any studies that demonstrate this effect. Interestingly however, Arditi and Cho seem to have generated results that may contradict the consensus opinion but I need to read a more detailed description of their study before reaching that conclusion.
As many of you have rightly pointed out, there are many other factors that come into play when studying the readability of program source code, such as colour etc. Some of you have asked what the reason for my question is or indicated that you don't think it is a relevant question to ask in the context of designing tools to increase programmer productivity. Fear not - Microsoft is not working on a new version of Visual Studio that will enforce mixed case variable naming conventions etc. Rather, I'm interested in this topic from the point of view of writing coding guidelines for class names, method names or parameters that are typically abbreviated, such as XML (or Xml).
