Database PL/SQL

I have to make an assignment for school but I get two errors:

Encountered the symbol "FETCH" when expecting on of the following: constant exception <an identifier> <a double-quoted delimited-identifier> table LONG_ double ref char time timestamp interval date binary national character nchar

and

Encountered the symbol "end-of-file" when expecting one of the following: end not pragma final instantiable order overriding static member constructor map

Here is the link to my code: http://pastebin.com/h4JN9YQY
