There are two environment variables that need to be set for the 2.11 Toolbox to run properly. The first is $HOME, which should point to your home directory. The second in $TOOLBOX, which should point to the directory where the Toolbox software is installed. Note that under Korn or Bourne shells, or their derivatives, these variables need to be exported, using the UNIX export command. Under C shell, environment variables are automatically exported. These variables should be set in your .cshrc, .profile, or other initialization file, so that they will be set automatically when you start a UNIX session.

There are several directories under the one pointed to by $TOOLBOX:

• amls/: Various AML, menu, and icon files used by the Toolbox
• docs/: Documentation files
• help/: User customizable help files
• misc/: Miscellaneous data files that support the interface

The following files will be stored in your $HOME directory, so each user can have their own personal configuration:

• .toolbox.cfg: Basic configuration parameters
• .toolbox.profiles: Link profile data
• .toolbox.system_settings: Menu positions and symbol data
  

Also, in each Toolbox working directory, two files are stored: arc.aml and coverages.dat.

• arc.aml: Not a Toolbox file at all - rather it is an ArcInfo initialization file that is automatically run when ArcInfo is started. If this file does not exist, create it. It should contain the following two lines:
  
  

  &amlpath $TOOLBOX/amls
  &menupath $TOOLBOX/amls
  

  Alternatively, these lines can be entered manually at any ArcInfo prompt before running the Toolbox.

• coverages.dat: A list of coverages used by the Toolbox in each working directory, allowing the user to have different network models with different coverage names. This file can created by running the configure program.
