Short: Shell help-key macro for ARexxGuide
Author: Robin Evans

DESCRIPTION
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is a little ditty that might be of some limited utility with
directory utilities or shells. The opening comment to the program
offers a suggestion of how it might be used with WShell.

The script takes one argument, a word. It then attempts to find that
word in the ARexxGuide cross-reference file. If it is sucessful, the
node for the word will be shown.

REQUIRED FILES
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   ARx_Help.rexx     Place in rexx: directory.
   ARx_Guide.xref    An AmigaGuide cross-reference file. Place in
                     directory with other ARexxGuide files.

OTHER REQUIREMENTS
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The shareware file ARexxGuide is required. It can be found on Aminet in
the util/rexx directory as file name ARexxGuide1_0A.lha.

AmigaGuide (available on Aminet) or Multiview is required to run ARexxGuide.

The freeware library rexxarplib.library is useful for this macro, but not
necessary.

SETUP:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Two environmental variables must be set for this file:

   amigaguide/path         May include multiple directories, but one of
                           them must be the full path to the directory
                           where ARexxGuide files are located. Without
                           this env: variable, the macro script will not
                           be able to load ARx_Guide.xref. The current
                           version of the script aborts if that happens.
                           Previous versions didn't check. AmigaGuide
                           would sometimes cause gurus since it was sent
                           invalid information.

   arexxguide/agcmd        Must hold the command used to start whatever
                           utility will be used to launch the ARexxGuide
                           files. It can include a full path, if
                           necessary. The current version of the script
                           aborts if this variable is not set, but doesn't
                           check for the existence of the command.

The macro ARx_Help.rexx should be moved to your REXX: directory. The file
ARx_Guide.xref should be moved to the directory where the other files in
the ARexxGuide archive are stored.
