-**   (2) EXPLAIN   The keyword EXPLAIN has been seen at the beginning of 
-**                 a statement.
-**
-**   (3) CREATE    The keyword CREATE has been seen at the beginning of a

-**                 TEMP or TEMPORARY
-**
-**   (4) TRIGGER   We are in the middle of a trigger definition that must be
-**                 ended by a semicolon, the keyword END, and another semicolon.
-**
-**   (5) SEMI      We've seen the first semicolon in the ";END;" that occurs at
-**                 the end of a trigger definition.
-**
-**   (6) END       We've seen the ";END" of the ";END;" that occurs at the end
-**                 of a trigger difinition.
-**
-** Transitions between states above are determined by tokens extracted
-** from the input.  The following tokens are significant:

-**   (0) tkSEMI      A semicolon.
-**   (1) tkWS        Whitespace

-**   (4) tkCREATE    The "create" keyword.

-**   (6) tkTRIGGER   The "trigger" keyword.
-**   (7) tkEND       The "end" keyword.
