RETURN without GOSUB (ERR: 3)
■ The program just executed a RETURN statement without
  executing a GOSUB statement.
 
■ Possible solutions:
 
  • Insert a GOSUB statement and disable all other entry
    points to the SUB procedure where the RETURN statement
    is defined.
 
  • Delete the RETURN statement.
