You have to search in the IDL help index. Typing
IDL> ?
will start the help system. On Windows, a Windows Help File will be
opened, where you can go to "Index" on the second tab. I don't have
access to IDL on Linux at the moment, but I think Acrobat reader will
pop up and you should also be able to find an index somewhere. Have a
look at the thread "Adobe Reader 7.0 in IDL?" from 04/14 on this
newsgroup for alternatives (xchm or IDLWAVE).
You can't find "power" in the help index? Be creative. Search for
"exponentiation", and you'll find what you are looking for. Searching
for "log" will give the the answer right away. Also, searching for
"operator" will list a lot of useful stuff.
Good luck,
Benjamin
PS: ^ does exponentiation, alog() and alog10() do natural and base-10
logarithm

I am sorry again, but you can't be serious, right? Have you ever typed '?'
to get help in IDL??? Under IDL Language Reference you find a functional
list of routines. Cehck the Mathematic section. (Please don't tell me that
you have spent a long time on this issue as well.)
