Dear David: I was using IDL and none of my colors are working.  I blame
you.  Why doesn't IDL work?  I run something and the vectors are wrong
but it didn't even work once.  What did you do wrong?  Also, I can't get
to the 4th row of my vector.  If Idl weren't so stupid I would be able
to.  Write a program to show me how to do the problem I have.  It's #4
of the last homework in my class.  It's really long.  I looked on your
web page but you didn't tell me how.  It's due today and IDL isn't very
fast or I would be done already.
