Getting Help with IDL
IDL's online help system provides access to information on all aspects of IDL. The complete IDL documentation set is available online in HTML format. To use the IDL online help system, do one of the following:
- Enter the
?command (optionally followed by a routine or object name) at the IDL command prompt - Call the ONLINE_HELP procedure at the IDL command prompt or within an IDL program
- If you are running the IDL Workbench, select the Help → Help Contents option from the menu bar
- Select IDL Help from the Microsoft Windows Start menu
- Double-click on the IDLHelp Macintosh icon
IDL's online help system is described in detail in Using IDL Help — located, appropriately enough, in the IDL online help system.
