Running IDL

To run an IDL program, or to enter an interactive session, just enter idl at the Linux prompt, or idlde for the more "convivial" form:

In the next sections, I will only present the command lines use of IDL, but anything done in IDL is possible in IDLDE.

There is a color mode available in Xemacs.

When you are under IDL, the prompt change to:

IDL>

and you can already type commands:

IDL> print , 'Hello World'

To exit IDL, type :

IDL> exit

or Control-D.
