Defining Additional Help Topics

ICL includes a HELP command which provides on line documentation on ICL itself. Using the DEFHELP command it is possible to extend the facility to access information on the commands you have added. In order to do this you need to create a help library in the normal format used by the VMS help system. This is described in the VAX/VMS documentation for the librarian utility. You can then specify topics from this library which will be available using the ICL HELP command using a command of the form

    DEFHELP  EDIT  LIBRARY.HLB

This will cause a

    HELP EDIT

command to return the information on EDIT in help library LIBRARY.HLB rather than in the standard ICL library.
