What entry in the base reference is that under? I'd like to look that up in the Stata 10 manuals. Thanks.

Did you enclose your r(macro) in single quotes?

Page 1673 of the Base Reference states the following technical note:

For r(macro), you are supposed to refer to it in quotes: `r(macro)'.
If, however, you omit the
quotes in an expression context, Stata evaluates the macro and then
pretends that it is the result of
function-returning-string. There are side effects of this, the most
important being that the result is
trimmed to 80 characters.

When writing a small program that saved a string (list of variables) using
-rclass- and -return local-, the list was prematurely truncated. I therefore
wonder if there a limit to the number of characters that can be stored in a
local macro using rclass, or if I should be looking for a bug in my code?
Many thanks,
