  The effects of the OK, Apply, Reset, and Cancel buttons
  are as follows:

   o  OK Button -- Click on the OK button to update the
      current configuration to reflect the compilation
      options you have chosen.  This action also removes
      the auxiliary dialog box in which the OK button
      resides.

   o  Apply Button -- Click on the Apply button to update
      the current configuration with any changes you have
      made to the compilation options.

      The auxiliary dialog box remains in effect when you
      click on the Apply button.  This allows you to
      establish or change several options during a single
      invocation of the auxiliary dialog box in which the
      Apply button resides.  Thus, you can set the
      options with the Apply button either one at a time
      or as a group.

   o  Reset Button -- Click on the Reset button to purge
      any options that you have chosen but not applied to
      a configuration (with the Apply button).

      The auxiliary dialog box containing the Reset
      button remains in effect when you click on the
      Reset button.

   o  Cancel Button -- Click on the Cancel button to
      purge all options that have been chosen but not
      applied to a configuration (with the Apply button).

      This action also removes the auxiliary dialog box
      in which the Cancel button resides.

      The main dialog box remains in effect when you
      click on the Cancel button.  This allows you to
      establish or change more than one configuration of
      compilation options without having to exit and
      reenter the main dialog box.
