Properties of the code
Produce 64-bit code
Allows procedure recursion when the RECURSIVE attribute has not been specified
Old synonym for /ISO option.
Win32 only. Appends "__C" to C_EXTERNAL
aliases that do not start with a double underscore.
Converts fixed-format source into free-format, output to the screen. All
comments are lost and Hollerith constants replaced with strings. This is useful
for converting fixed-format INCLUDE files into files suitable for both fixed
and free formats. This option implies the /NO_BINARY option and no error
checking, other than for matching brackets and checking the fixed-format column
rules, is done. All other options on the command-line are ignored.
only. Supplies a fully qualified class name to
hold the Fortran code when used with /LINK.
Causes DO loops to be executed at least once to allow certain Fortran 66
programs to execute correctly.
Win32 only. Applies the F_STDCALL keyword to
all user-defined and imported subprograms. Standard intrinsics, FTN95
intrinsics and FTN95 library routines are automatically excluded. FTN95
routines such as CISSUE must be renamed CISSUE@. Certain Fortran language
restrictions apply and, in particular, INTERFACE statements may not
be used with this option. When used with /CHECK, certain checking processes are
not implemented. In particular, what are called "write-ability" checks are
not applied. This means that it is advisable to test your code using
/CHECK (or /CHECKMATE say) without using /F_STDCALL.
Permits the use of some Fortran 200x statements as an extension.
Accept source code in ISO fixed source format. This is assumed for files with
.FOR or .F suffixes. If the name of the source file on the command line has no
suffix and this option is supplied then .FOR is assumed to be the suffix.
Accept source code in ISO free source format. If the name of the source file on
the command line has a suffix which is not .FOR and not .F, this option is
assumed. If the name of the source file on the command line has no suffix, .F90
Fault on IMPLICIT type definitions.
Allows specification of list of include paths. This is appended to the list of
include-paths optionally specified in the environment variable F95INCLUDE.
Ensures that all constructs used in a program conform to the Fortran 95 ISO
Standard. The /ISO option also informs the FTN95 run-time system that
ISO-conformity is required. This means that, for example, non-standard use of
format descriptors (such as business editing in a run-time format) causes a
run-time fail ure.
Specifies that the source code uses Apple Macintosh end-of-line characters.
Sets alternative path for module files. More than one /MOD_PATH is permitted.
This is appended on to the path contained in the optional environment variable
INTEGER A(1) implies INTEGER A(*) when declaring procedure arguments.
only. Implied by /CHECKMATE. Can be used in
release mode to trap overflow by planting a call to CHECK_FINITE@
after every floating point calculation.
Do not use the stack for storage of local variables and arrays. Otherwise
dynamic storage is used for all local variables and arrays. This has the effect
of a blank Fortran SAVE statement in each subprogram. Its use should normally
only. Sets stack size per thread when using
/LINK or /LGO.
Win32 only. Used to trap underflow.
Display version information.
Win32 only. Program is compiled for use with
All static variables and arrays set to zero at start of execution.
