You can share common help between commands.
The previous section describes how to create a panel group that contains help modules for just one command. Because of the naming scheme used for connecting command online help modules with a command, you could store the help modules for many commands into a single panel group. When help modules for several related commands are in a single panel group, you can use :IMHELP. (Imbed Help) UIM tag to share common help information. For example, you might have several commands that have a parameter named OUTPUT, which has the same general description on each command. Sharing the same command help information ensures consistency across all the commands that have this parameter.
Another option for sharing online help text is to use the :IMPORT. (Import) UIM tag, which lets you define one or more help modules that are in another panel group that can be imbedded dynamically using :IMHELP tags.
