Getting Help

IRAS90 includes an on-line help library which contains most of the information contained in this document, in a hierarchical VMS-like form. It can be accessed in several ways:

• The command I90HELP (or i90help on UNIX) will put the user at the top level of the help library. The user can then navigate through the help library using the usual VMS techniques (even on UNIX).
• When an IRAS90 application issues a prompt, the user can respond with a single or double question mark (``?'' or ``??''). The former displays the description of the current parameter from the help library and then re-issues the prompt for the parameter. The latter displays the same information, but leaves the user in the help library, thus allowing other information to be examined. The parameter prompt is re-issued when the help library is finally exited.
• Within ICL, the command

       ICL> HELP <application>
  

  will display information about the specified IRAS90 application. Note, the application must be specified on the HELP command line as shown. The user will be left in the IRAS90 help library after the information has been displayed.
