  ERROR - The program contains a syntax error.  BASIC assumes a  keyword
  is  missing  and  continues  compilation under that assumption so that
  other errors  may  be  detected.   The  actual  program  line  remains
  unchanged  and no object file is produced.  Examine the line carefully
  to discover the error.  Change the program line to correct the  syntax
  error.
