DBMS_JOB.SUBMIT problem

Can anyone tell me why the following code generates a run-time error (replies to rs_at_rshome.u-net.com please)...

ORA-06550: line 1, column 114:
PLS-00103: Encountered the symbol "END" when expecting one of the following:

   := . ( @ % ;
The symbol ";" was substituted for "END" to continue.
