What is your full script? Just adding flags to a variable is not going 
to do anything.

Either leave out the variable:

setflag "spam";

In which case it applies implicitly to subsequent fileinto and 
(implicit) keep.

Or use the "${flagvar}" variable in a fileinto or keep command:

fileinto :flags "${flagvar}" "Mailbox";

Or

keep :flags "${flagvar}";

Regards,

Stephan.
