Stata friends,

Is there a simple way to see how much time has elapsed while a command in
the midst of a "for" loop is running?

Outside of a loop, I just "set rmsg on" and can see how long each command
takes.

But if I have, for example,

for num 1/10: preserve \ keep if age==X \ reshape [blah blah blah] \
save ageX.dta, replace \ restore;

and I want to know how long the reshaping took, I'm not sure how to find
out. "set rmsg on" only gives me the time for the entire loop.

I know about macros to display the time, but I'm not sure how to
manipulate them to calculate time elapsed.

Thanks so much,
Dave
