More Information

 The HELP statement gives you access to assistance on all SQL
 statements, components, and concepts.  When you type HELP:

  o  A menu of topics on which assistance is available replaces
     the SQL> prompt.

  o  After the menu scrolls by, the cursor remains at a "Topic?"
     prompt.  Typing any of the menu items yields assistance on
     that topic.  Many of the topics have further levels of
     assistance, indicated by a "Subtopic?" prompt.

  o  To move back to the next higher level, press the RETURN key.
     For example, pressing RETURN at the "Subtopic?" prompt
     brings you to the "Topic?" prompt, and pressing RETURN again
     returns you to the SQL> prompt.

  o  To see the list of additional topics at any level, type a
     question mark (?) and press RETURN.

  o  To leave Help, enter CTRL/Z or, at the "Topic?" prompt,
     press RETURN.
