  SEVERITY:  I

  MESSAGE TEXT:  Questionable branch into loop or block

  EXPLANATION:  A branch into a DO loop or IF block was detected.
  Although this might be valid if the FORTRAN 66 "extended range of a
  DO loop" feature was being used, it generally indicates a
  programming error.  A common case involves two or more DO loops
  which share a common termination.  In such cases, the shared
  termination statement is considered to belong to the innermost DO
  loop.
