Starting IDL

The easiest way to start IDL is by launching the IDL Workbench, which is an Eclipse-based graphical user interface.

You can also run IDL in command-line mode, which uses a text-only interface and sends output to your terminal screen or shell window.

IDL is available in both 32- and 64-bit versions. You can execute the 64-bit version only if your system supports 64-bit operations, but you can run the 32-bit version on a 64-bit system. On 64-bit systems, you can explicitly specify the 32-bit version by adding the -32 flag or selecting a 32-bit IDL icon when launching IDL. See Command-line Options for IDL Startup  for details.

The following table lists the various ways to launch IDL:
