So, when is this evaluated? Clearly, from your response, it's not at compile time. Clearly, as well, if I enter an expression (such as my first example) it's evaluated NOW (which I would have understood as "compile time"). What about the other possible expressions I listed? Can I use an memory variable (that will exist at run time) or call a UDF?

Thanks yet again.

='abc'+chr(13)+'def'

>>Now, I've never seen any documentation on this feature, so I have a few questions. What are the limitations on what I put after the equal sign? When is it evaluated? Which of the following, if any, make sense?

=m.SomeVariable
>>=clr_Purple && where clr_Purple is #defined in an include file
>>=SomeUDF(...)
