/sys$common/syshlp/helplib.hlb FORTRAN, Statements, OPTIONS  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  Overrides qualifiers specified by the FORTRAN command (for a single
  program unit).  Statement format:

   OPTIONS option [option...]

   option  Is one of the following:

     /ASSUME=(ALL, [NO]ACCURACY_SENSITIVE, [NO]DUMMY_ALIASES,
              NONE)
     /NOASSUME

     /BLAS=(ALL, [NO]INLINE, [NO]MAPPED, NONE)
     /NOBLAS

     /CHECK=(ALL, [NO]ALIGNMENT, [NO]ASSERTIONS, [NO]BOUNDS,
             [NO]OVERFLOW, [NO]UNDERFLOW, NONE)
     /NOCHECK

     /CONVERT=(BIG_ENDIAN, CRAY, IBM, LITTLE_ENDIAN, NATIVE,
               VAXD, VAXG)

     /[NO]EXTEND_SOURCE
     /[NO]F77
     /[NO]G_FLOATING
     /[NO]I4
     /[NO]RECURSIVE

  You must place a slash (/) before the option.

  The OPTIONS statement must be the first statement in a program
  unit, preceding the PROGRAM, SUBROUTINE, FUNCTION, and BLOCK DATA
  statements.

  OPTIONS statement options have the same syntax and abbreviations as
  their similarly-named OpenVMS compiler options.

  OPTIONS statement options override compiler options, but only until
  the end of the program unit in which they are defined.  Thus, an
  OPTIONS statement must appear in each program unit in which you
  wish to override the compiler options.
