Hello, all.
I want to customize IDL's online help.
According to "IDL User's Guide", the system variable "!HELP_PATH"
indicates the directory that contains help file for online help.
But, this system variable is somewhat strange.
When executing the HELP command,
IDL> help,!HELP_PATH
help,!HELP_PATH
^
% Not a legal system variable: !HELP_PATH.
When I try changing this system variable,
IDL> !HELP_PATH=!HELP_PATH + "~/idl/help"
!HELP_PATH=!HELP_PATH + "~/idl/help"
^
% Not a legal system variable: !HELP_PATH.
!HELP_PATH=!HELP_PATH + "~/idl/help"
^
% Not a legal system variable: !HELP_PATH.
How can I change the system variable, "!HELP_PATH" ?
I use IDL version 3.0

I think your problem is that your documentation is for a later version of IDL
than the one you're using. Looking at the release notes, it appears that
!HELP_PATH was added with version 3.1.0.
