First of all, you should be using cgImage, rather than
TVImage, if you just downloaded the Coyote Library.
TVImage is very old. You should use the latest routines.
In changing your "path", you have apparently removed
the normal IDL "lib" directory from your IDL path,
as this is where StrSplit is found. You want to restore
the <IDL_DEFAULT> directory back to your IDL path. You
will need this for MANY things besides the Coyote Library. :-)
You may find it difficult to learn to use IDL if you
are just coming to computer programming for the first
time. It has a few quirks.
If you think a book would be helpful, I would highly
recommend you find a copy of Ken Bowman's book, An
Introduction to Programming with IDL. I think you will
find many of your questions about defining variables
and programming in general answered in that book.
Cheers,
David
