VMS Help FORTRAN, /ERROR_LIMIT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  /[NO]ERROR_LIMIT[=n]            D=/ERROR_LIMIT=30

  Specifies the maximum number of E-level or F-level compiler errors
  allowed for a given compilation unit.

  Error counts are not accumulated across a sequence of compilation
  units.  If you specify /ERROR_LIMIT=n, each compilation unit can
  have up to n - 1 errors without terminating the compilation.  When
  the error limit is reached within a compilation unit, compilation
  of that unit is terminated, but compilation of following units
  continues.

  The /ERROR_LIMIT=0 option is equivalent to ERROR_LIMIT=1.  If you
  specify /NOERROR_LIMIT, there is no limit on the number of errors
  that are allowed.

  By default, execution of the compiler is terminated for a given
  compilation unit upon the occurrence of the 30th E-level or F-level
  error within that unit (equivalent to /ERROR_LIMIT=30).
