     You can use the Environment Variables dialog box to define new
     environment variables and clear existing ones.
 
     To define a new environment variable:
 
       1. Type the variable definition in the Variable text box.
 
          The variable definition takes the same form as the argument
          to the operating-system SET command. That is, the name of the
          variable is followed immediately by an equal sign (=) and the
          value of the variable. For example:
 
               INIT=C:\INIT
 
       2. Choose Set Variable.
 
     To clear an existing environment variable, use one of the
     following methods:
 
       ■  Type a new (empty) definition:
 
            1. Type the name of the variable in the Variable text box,
               followed by an equal sign. For example:
 
                    INCLUDE=
 
            2. Choose Set Variable.
 
       ■  Edit an existing definition:
 
            1. Select the variable from the Variables List box.
 
            2. Delete the text after the equal sign.
 
            3. Choose Set Variable.
 
     To cancel your changes and restore the environment table to the
     value it had before you opened the dialog box:
 
       ■  Choose Cancel.
