Fortran 95 (Win32) language systemSpeed. Dependability. Great Tech Support. Lahey/Fujitsu Fortran 95.
The standard for Fortran programming from the leader in Fortran
We've combined our 37 years of producing award-winning Fortran
language systems with Fujitsu's compiler expertise and
high-performance code generator to deliver the most-productive,
best-supported Fortran 95 language system for the PC. Whether
you write new Fortran programs or downsize existing
applications, you need speed, dependability, and great tech
support. You need LF Fortran v7.1!
LF Fortran v7.1 Delivers!
Important features include ...
LF Fortran 95 Performance.
LF Fortran 95 7.1 offers improved execution performance on most
Fortran 77 and 90 codes. The new optimizations help performance
on Pentium(R) 4 and Xeon(TM) chips. "We tested v7.1 Win32
optimizations on a 2.4GHz P4 with 512 MB of PC2100 RAM, running
Windows XP, using Polyhedron?s (www.polyhedron.com) Fortran
benchmarks. Specifying the new switches -tp4, -sse2, -zfm, -o2,
and -inline the 90 benchmarks ran an average of 15.4% faster and
the 77 benchmarks 4.4% faster than they did when built with LF
LF Fortran 95 Optimizations.

LF Fortran 95 supports static linking with Fujitsu C and Microsoft
Visual C++ version 2.0 and greater. Combine your Fortran and
C/C++ code into one executable. For the routines you don't want
to develop yourself, you can also link with C/C++ routines from
commercially available libraries.
DLL Interfaces to Visual Basic, VC++, Borland C++, Delphi, Microsoft
Create 32-bit Windows DLLs from your Fortran routines and call the
Fortran routines from 32-bit Windows programs created with
Microsoft Visual Basic, Microsoft Visual C++, Borland C++,
Borland Delphi, and Microsoft .NET languages.
Win32 API Access.
LF Fortran 95 supports direct calls from Fortran to functions in
the Win32 API. For a narrow range of applications, this might be
the last little bit of glue you need to pull off your project.
Note that this is not for the faint-hearted! You'll need to be a
Windows programmer to get all but the most basic functionality.
That's because the API was written to be called from C. And
consequently, arguments need to be passed as C expects them.
Structures and callback routines pose additional problems.
Clearly, this would be a difficult way to build a Windows
application from scratch.
Legacy Fortran Support.
LF Fortran 95 extends its language support in other directions
adding many legacy Fortran features, including VAX structures
and the various UNIX service routines. These features further
facilitate your move to cost/performance efficiency on the PC

LF Fortran 95 is a complete implementation of the ANSI/ISO Fortran
95 standard. Fortran 95 offers some small but important
improvements over Fortran 90, including the ability to create
your own elemental procedures, default initialization for
structure components, the NULL intrinsic for initializing
pointers, the FORALL construct, and a standard CPU_TIME
IEEE Standard 754 support
IEEE Standard 754 defines the representation and behavior of 32- and
64-bit floating point numbers. IEEE 754 support provides for
consistency of basic computational results among platforms that
use IEEE 754. An excellent overview of the standard is presented
online by Steve Hollasch at http://research.microsoft.com/~hollasch/cgindex/coding/ieeefloat.html.
A heavy-duty online discussion of floating point numbers and the
standard is provided by David Goldberg at http://docs.sun.com/source/806-3568/index.html.
Integration files are provided to support using the LF Fortran 95 compiler
within MATLAB. These files provide seamless integration with
MATLAB and external API procedures. MATLAB example code should
not require any modification when LF Fortran 95 support is
Visual Studio .NET 2003 Development Environment.
Visual Studio .NET 2003
Visual Studio .NET 2003 is the industry standard in development
environments. The Win32 Visual Studio integration includes
project management facilities, project/code templates, on-line
integrated help, and Fortran-smart editing.
Win32 Project Types
Additional Project Types Supplied with Visual Studio
- Empty Project (Win32) provides a solution
and project without any source files. The user can add items
to this project by using the "Project/Add New
Item" menu selection.
- Static Library (Win32) consists of a
library project, example subroutine, and function
procedures. The user should change the procedure name,
function result type, and argument list to suit. If either
the function or subroutine is not required, it may be
removed. When compiled, this project type creates a library
file with the .lib extension, which
may be called by other native Fortran 95 applications.
- Dynamic-Link Library (Win32) consists of
a DLL project and example subroutine and function
procedures, which are marked for export. The user should
change the procedure name and export list, function result
type, and argument list to suit. If either the function or
subroutine is not required, it may be removed. When
compiled, this project type creates a dynamic link library
with the .dll extension, which may be
called by any application (including .NET managed
applications) that can import the procedures.
- Console Application (Win32) consists of a
console project and a skeletal main program. The user should
change the program name to suit. When compiled, this project
type creates a console application. If this application is
invoked from a console, it executes within the console. If
the application is invoked from an icon, the Run menu, or
Windows Explorer, it creates a console to run in, and
destroys the console when the program completes execution.
- WiSK Simple Application (Win32) this is a
project that opens a window, handles a close request, and
contains an empty resource file. This project type compiles
into a Windows GUI application.
- WiSK Skeleton Application (Win32) this is
a project that opens a window containing a menu, and
captures a number of events, such as keydown, mouse button
and mouse move events, menu selection, pushbutton, expose
and resize events. It contains a resource file which defines
menu items. This project type compiles into a Windows GUI
On-line Integrated Help
- Setup and Deployment Project allows the
programmer to create installation programs that can ease the
task of distributing .NET applications. A setup project
packages the files that comprise an application and
facilitates the creation of directory structures.
- Database Project provides a means of
manipulating databases and designing and executing SQL
scripts and queries without having to create an application.
The on-line integrated help provides Fortran for .NET
installation and getting started instructions, a Fortran for
.NET Users Guide, and a Fortran for .NET language reference. It
also includes the MSDN Library and Visual Studio SDK help.
The Fortran for .NET language system provides the Visual Studio
editor with the smarts to recognize and color-code Fortran
Fortran-Smart Windows Debugger
The WinFDB debugger provides a Windows graphical
interface for debugging your Fortran code.

Other Development Tools
Complementing the Windows Development
Environment, LF Fortran 95 includes the Microsoft's make utility
(nmake), Automake make utility; Microsoft's library manager
(lib) and Lahey's Library Manager (LM) for building and working
with library files; and Microsoft's linker (link).
Winteracter Starter Kit.
Use the Winteracter Starter Kit - WiSK
- for creating true Windows programs with Fortran. WiSK
is a subset of the Winteracter Library created by
Interactive Software Services, Ltd. (Winteracter is
available from Lahey.) Winteracter is a Fortran
95-callable, 32-bit, Windows, user-interface and graphics
development kit. Derived from Winteracter, WiSK
provides a library of subroutines for window management, input
handling, dialog management, and high resolution graphics, plus
custom versions of the visual menu and dialog designers.
Fujitsu Visual Analyzer.
Visually analyze the call structure and logic flow of your Fortran and C
source code. Display a detailed cross reference of all the
variables in the program and where modules and commons are
defined and referenced. Show C global variable definitions and
references as well. VA can help you understand someone else's
code, detect subtle programming errors across multiple files,
and verify compliance with the Fortran 95 standard.
LF Fortran 95 beta tester Barry Santana says, "Fujitsu Visual
Analyzer has been a great help in avoiding conflicts in the
modifications. The help that Lahey Technical Support has
provided quickly and without hassle has provided this project
with a much needed shot in the arm! It has confirmed that my
decision to switch to the Lahey compiler was correct. Thanks for
all the help."
