  ERROR - A DIMENSION statement names an array already declared  with  a
  DECLARE,  COMMON,  MAP,  or RECORD statement, or one that was declared
  statically in a previous DIMENSION statement.  Remove  the  executable
  DIMENSION statement or originally declare the array as executable in a
  DIMENSION statement.
