To access the KAPPA help use KAPHELP.
The system responds by introducing KAPPA's help library, followed by a long list of topics for which help is available, followed by the prompt Topic?. These topics are mostly the commands for running applications, but they also include global information on matters such as parameters, data structures and selecting a graphics device.
From ICL you can issue other commands for obtaining help about KAPPA.
ICL> help kappa ICL> help packages
The former is nearly equivalent to entering kaphelp. However, it is less easy to use as it lacks many of the navigational aids of KAPHELP. The latter gives a summary of Starlink packages available from ICL. If you select the KAPPA subtopic, you'll get a precis of the package's facilities. (This is part of an index of Starlink packages.)
If you have commenced running an application you can still access the help library whenever you are prompted for a parameter. See Entering the Help System for details.
