... that macro expansion works inside of quotes? I just ran across this in someone else's code, and thought that it was a bug for sure. You learn something new every day, although I'm not sure when I would have the need for this. More importantly, this behavior could produce a bug if you're not expecting it . An example is below.

cMacro = "Test"
? "&cMacro"  && returns "Test"
? cMacro  && this is how most people would do it
? "&cAnotherMacro"  && returns "&cAnotherMacro" since variable doesn't exist.

Example producing unwanted results:
D = "Test"
? "R&D"  && returns "RTest"
