1. Fortran-Smart Windows Development Environment
Fortran-Smart Windows Editor
Lahey ED for Windows
leads the way in intelligent, language-sensitive editing. Up and running
straight out of the box for the new user but still highly configurable,
ED fits the way you want to work:
Errors: Lahey ED automatically highlights syntax and semantic
errors generated by the compiler and positions the cursor on the offending
line in your source code.
Errors: Color syntax highlighting makes errors obvious and dramatically
reduces compile-edit cycles.
Time: Drag & drop text using the mouse. Right click to look
up functions in other source files, open include files, and do bracket
Productivity: Lahey ED formats and writes code for you with
smart indenting, code templates, auto-correction, code completion, and
automatic case conversion. You'll produce legible, correct code quicker
than ever before.
Fortran-Smart Windows Debugger
Lahey's Source On-Line
Debugger is part of Lahey ED for Windows. You can edit, compile, link,
execute, and debug your program all from within the editor. Windows SOLD
helps you detect and correct programming errors quickly:
execute your program: Single step through your program. Step
into or over calls to other routines.
on Break Points: Click in the margin of your source code to
set break points.
Variables: Right click on a variable to display its value.
Variables: Open a watch window to show variable values in any
active program unit.
DLLs: Debug LF90 DLLs called by LF90 programs.
Additional Bundled Tools
Windows Development Environment, LF90 includes a 32-bit extended-DOS debugger
and execution profiler, the Automake make utility with interactive configuration
file editor, librarian, and the Phar Lap TNT DOS-Extender, Linker, and
Virtual Memory Manager.
2. Fujitsu Visual Analyzer.
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 90 standard.
3. Fujitsu Scientific Subroutine Library 2.
The Fujitsu Scientific
Subroutine Library 2 (SSL2) has been in use for years in Japan on Fujitsu
mainframe and workstation hardware. It is now included with LF90 v4.5.
SSL2 offers over 250 optimized routines in the following areas:
Matrix Storage Mode
and Matrix Inversion (Direct Method)
Least Squares Solution
Eigenvectors of a Real Matrix
Eigenvectors of a Complex Matrix
Eigenvectors of a Real Symmetric Matrix
Eigenvectors of a Hermitian Matrix
Eigenvectors of a Real Symmetric Band Matrix
Eigenvectors of a Real Symmetric Generalized Eigenproblem
Eigenvectors of a Real Symmetric Band Generalized Eigenproblem
Function with a Variable
of Multivariable Function
of Sum of Squares of Functions (Nonlinear Least Squares Solution)
(Constrained Minimization of Multivariable Function)
Discrete Real Fourier
Discrete Sine Transforms
Differentiation and Quadrature
Sine and Cosine
Pseudo Random Generation
Pseudo Random Testing
State-of-the-Art Intel Pentium and Pentium Pro Optimizations
Code runs fast with
LF90. LF90's Intel-designed code generator uses common optimization techniques
as well as instruction scheduling, loop unrolling, loop interchange, loop
distribution, strip mining and pre-loading, loop blocking, and alternate
loops. The alliance of Lahey and Intel technology has produced a Fortran
90 to handle the most demanding code.
DOS, Windows 3.1x, Windows 95 and NT Support
Create Windows 3.1x,
Windows 95, Windows NT, and Extended-DOS Fortran applications. Create Windows
applications with the Winteracter Starter Kit,
or by calling the Win32 API directly from LF90 code, or
through 32-bit Fortran DLL interfaces to Windows programs
created with other language systems. Create extended-DOS applications with
the bundled Phar Lap DOS Extender. Extended-DOS applications run from all
Windows' DOS prompts.
LF90 v4.0, the driver, compiler, linker, librarian, and make utility are
32-bit, Windows executables. These tools offer improved performance under
Windows NT and support the use of long filenames. These same tools are
also bound to the Phar Lap TNT DOS-Extender and Virtual Memory Manager
-- you can use the same tools under DOS.
Enhanced Winteracter Starter Kit
LF90 v4.5 includes
an enhanced 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, US$675.) Winteracter is a Fortran 90-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. The enhanced
WiSK offers semi-modeless dialog boxes, radio buttons, improvements
to the visual dialog and menu editors, and a handful of miscellaneous new
menu designer, MenuEd, allows you to create menus in the conventional
Windows horizontal format or as Windows 95 and NT floating menus. MenuEd
saves menu layouts as reusable resource scripts. LF90 automatically compiles
these scripts with the resource compiler and links the menus into your
WiSK program. MenuEd also saves a Fortran source file containing
PARAMETER statements defining identifiers for each item in the menu resource
file. This file can be USE'd or INCLUDE'd by a WiSK program allowing
you to reference items in the menu using meaningful names.
dialog designer, DialogED, allows you to interactively create Windows
dialogs. Like MenuEd, DialogEd generates resource scripts
and module or include files defining the identifiers of each dialog control.
Various standard field types and controls are supported including string
fields, list boxes, combo boxes, group boxes, push-buttons, picture frames,
and labels. DialogED also offers a "test" button to try out your
dialogs without having to build or rebuild your application.
Statically Link with VC++ and Borland C++ object files.
Version 4.5 of LF90
supports static linking with Microsoft Visual C++ version 2.0 and greater
and with Borland C++ version 4.5 and greater. Now you can 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
DLL Interfaces to Delphi, Borland C++, Visual Basic, and Visual C++
Create 32-bit Windows
DLLs from your Fortran routines and call the Fortran routines from 32-bit
Windows programs created with Borland Delphi, Borland C++, Microsoft Visual
Basic, and Microsoft Visual C++.
Win32 API Access
LF90 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.
Portable User Interface and Graphics Routines
LF90 includes the
Lahey/INTERACTER Starter Kit (LISK). LISK is a collection of portable
user-interface and graphics routines. LISK allows you to include portable
GUIs and screen graphics in your programs using only Fortran code.
Because LISK is a
subset of Interactive Software Services, Ltd.'s INTERACTER library,
customers can move their programs to Unix and VMS workstations supported
by the INTERACTER library. LISK offers routines of the following
kinds: character graphics, character manipulation, clearing, cursor control,
fixed-field input handling, general graphics, graphics character output,
graphics drawing primitives, graphics style selection, hardware identification,
informational, input parameter selection, keyboard and mouse handling,
menu handling, mouse cursor control, operating system interface, screen
manipulation, text attribute, text output, and window management.
Port Legacy FORTRAN 77 to the PC
LF90 is designed
to port legacy Fortran code from workstations, minicomputers, and mainframes
to the PC. LF90's 32-bit operation and 4GB capacity move large programs
easily without sacrificing performance. A collection of DEC/VAX and IBM/VS
intrinsics make porting even easier.
ANSI/ISO Compliant Fortran 90
Lahey Fortran 90
is a complete implementation of the ANSI/ISO Fortran 90 Standard. It incorporates
all of FORTRAN 77 and adds features that make Fortran 90 the language of
choice for scientific computing.
Fortran 95 Intrinsic Procedures
LF90 includes a
number of Fortran 95 intrinsic procedures. Intrinsic functions CEILING
and FLOOR now take the optional KIND argument. The functions MAXLOC and
MINLOC are extended with the optional DIM argument like those for the functions
MAXVAL and MINVAL. The functions MAXVAL, MINVAL, PRODUCT, and SUM already
have a DIM argument but, for consistency with MAXLOC and MINLOC, are extended
to allow their MASK argument as the second positional argument. The new
intrinsic subroutine CPU_TIME returns the processor time.
