If a restaurant is open between 7AM and 6PM, it
is generally not possible to have dinner there
after attending the theater. :-)

David,
I'm not a native English speaker and I cannot quite understand
what you mean in the reply. But I can sense that maybe you thought
me as a bad learner.
I'm a beginner of IDL, and I began to learn it by myself about two
weeks ago. With a brief guide from the web, I can write some useful
programs for my study now. I think it is great for me because I have
to
handle both the IDL and the English within such a short time. There
is
no newsgroup in my own laguage and few people around me are using
IDL.
So when I come across questions, I search on the web. As I'm not sure
what kind of keywords I should use for the search, I used both
'tm_test'
and 'loop'. So far, I have not found my answer so far.
Maybe you think I'm silly or lazy, but I DO did my effort to learn IDL
and tried not to bother others with simple questions. This is my
first
post on this newsgroup. No matter what you think of me, I'll keep
searching
for the answers.
