(Setting this in .cshrc or .tcshrc for an individual user also works.) The installation of IDL should be tested by typing idl at a shell prompt and seeing that a license is obtain. In addition, idlde should be tested to see that it starts the IDL development environment. IDL is used as the language for CPLOT Graphical Analysis Program.
