Examples

   1.$ PHONE

     The DCL command PHONE invokes the Phone utility. If you issue
     the PHONE command without qualifiers or parameters, the Phone
     utility prompts you for the name of the person you want to
     call (or any other PHONE command) with the default switch hook
     character, the percent sign. The Phone utility also displays
     the title "VMS Phone Facility", and the date, and sets up your
     viewport.

   2.$ PHONE ANSWER

     Use this command to answer a call.

   3.$ PHONE DIRECTORY TAMPA::

     The PHONE command causes the Phone utility to display a
     directory of users available on node TAMPA.

   4.$ PHONE /SWITCH_HOOK="\" /VIEWPORT_SIZE=5  EUGENE::MALCOLM

     The PHONE command defines the SWITCH_HOOK character to be the
     backslash (\), restricts the VIEWPORT_SIZE to five lines, and
     places a call to user MALCOLM on node EUGENE.
