Thank you for your comments, everyone!!! These tips are very useful to
modify my sourcecodes. Happy new year!!! (<- We have new years day
(lunar calendar) this weekend in Korea!)

Alternatively, a wall clock would do the job pretty well in this sort of scenario since
+/- 5 minutes is probably a high resolution measurement.
Unless, of course, he charges his time like a lawyer.... :o)

I think prehaps what the OP is looking for is a way to get the elapsed
time of execution of the code minus any time spent while he stops the
code to verify it is working properly.
Without knowing how the OP "stops" his code for these checks, it's not
really possible to know if it's possible. If he has coded a pause/
resume function then the time spent stopped in that function could be
calculated (as suggested above), and then subtracted from the total
execution time (calculated again as suggested above by bob).
Alternately I would suggest that the OP first makes sure that his code
works correctly, and then worry about execution time, thus removing
the need to stop mid run.
Regards,
Bob.

You can put your own statements in to check the time
elapsed between any lines in your code, whether it has stopped
or not.
starttime = systime(1)
dostuff
stoptime = systime(1)
print,'elapsed time in seconds: ',stoptime - starttime

Hello, Dr. Fanning,
Sorry for my broken English... (T.T)
If I run a sourcecode whose total running time is 28 hours, sometimes
I want to stop IDL intentionally to check whether the program is
running properly. Even in this case, can I have the running time of
it? If you are still missing something, (Mmmm... Can you speak Korean?
Just kidding... Sorry T.T) please reply me one more time.

I think I am missing something. If it is stopped
in the middle it is, uh, not running, verdad?
I've probably just been out of the country too long. :-)

Thank you for your invaluable infomation, Liam. However, in my
understanding, it seems that this function doesn't present running
time when I have to stop IDL in the middle of running process. What do
you think? Do you know how to make IDL print the running time on the
screen even stopped in the middle? Thanks.
