The Options menu allows you to tailor the CMS session
  by performing the following:

  o  Enter CMS command-line mode
  o  Specify options for the display of messages
  o  Open a specific library (or libraries) each time
     you invoke CMS
  o  Set up a list of known libraries for easy reference
  o  Set a default view to be displayed each time you
     invoke CMS
  o  Set default occlusion information
  o  Specify default restrictions for each view type
  o  Save and restore customized options

  Note that some customizations will take effect
  immediately, while others may take effect the next time
  you invoke the associated view, and still others take
  effect the next time you invoke the CMS DECwindows
  interface (for example, the Initial Library menu item).

  To save options, choose the Save Options menu item.
