Thank you, Nick and Martin. I set myself up for a sucker punch in my 
last message.

Still, even if single quotes can evaluate lots of different kinds of 
things, and r(varlist) is not a local macro kind of thing, what kind of 
thing *is* r(varlist) and what are the rules governing its use? Is it a 
function returning the contents of a macro, or something else? (And what 
are the other kinds of returns, like e(b), which acts more like a matrix 
than like the contents of a matrix, and yet does not support subscripting?)

Nick, thanks for the tip about your tips book. I do have a copy ... if 
only I could find it ... :(

Michael
