In Stata there are variables and local macros (locals for short) but
there is no such thing as a local variable. Keeping those appart can
safe you a lot of confusion. 

-summarize- is not the only command that returns results. Most Stata
commands return results. To see what is left behind you can type 
-return list- (or -ereturn list- after estimation commands). The trick
is to find a command that leaves the stuff you want behind in returned
results. If there is no such command you can often derive it from the
stuff that is returned. 

Modes are pretty tricky things, there is stuff out there that does do
some estimation on those, but if you don't really really need I would
stay away from that.
