Whenever the NAG Fortran Library has been supplied in compiled form, that form is considered to be the standard library file. The use of all supplied software must be in accordance with the terms and conditions of the Software Licence signed by NAG and each site. Any request to use NAG software on a computer other than the one licensed must be referred to NAG (see Section 6).
This implementation is a compiled, tested, ready-to-use version of the NAG Fortran Library that is considered suitable for operation on the computer systems detailed below:
hardware: PC compatible systems
operating system: Windows 95/98 or Windows NT
Fortran compiler: Salford FTN77/Win32 V4.02 or compatible (including FTN95
compilers - see Section 2.2)
For information about implementations of the NAG Fortran Library for use on other computer systems please contact NAG.
This implementation was produced at NAG Ltd., Oxford on the computing system detailed below:
hardware: Dan Technology PC6500 (400MHz Pentium II) operating system: Windows NT v4.0 (Service Pack 6a) Fortran compiler: Salford FTN77/Win32 V4.02 compiler options: /intl /logl /nolink /silent utilities: Intel MKL library, version 2.1
The implementation has also been successfully tested with Salford FTN95/Win32 V1.25 and V2.50.
Note that the options /intl /logl /nolink are set by default in the ftn77.opt file in the compiler directory.
The option /check was also used to compile the following routines:
e04abzt.for f01lzwt.for f02bjyt.for f06jmft.for g01arft.for g03baft.for s17aeft.for
The options /intl and /logl force the compiler to use long integers and logicals (INTEGER*4 and LOGICAL*4). The option /check plants extra code for various run-time checks.
See the Salford FTN77 compiler documentation for information on setting up the Salford FTN77 compiler system and a description of the compiler options.
This library has been tested using the Basic Linear Algebra Subprograms (BLAS) and linear algebra routines (LAPACK) provided by NAG (see the Chapter Introductions for F06, F07 and F08 in the NAG Fortran Library on-line documentation (PDF files)) only. It has also been tested using the BLAS in the Intel MKL library, version 2.1 (adapted for use with Salford FTN77 - see Section 4.1 for details).
For further details, refer to other documentation supplied or contact NAG (see Section 6).

The CD should autorun on Windows 95/98 and NT 4.0 systems, and will then lead you to a dialogue for installation.
If the autorun facility does not operate, then double click on the setup.exe file on the CD using Windows Explorer. Any continuing difficulties indicate a problem which should be reported to the NAG Response Centre (see Section 6).
The installation program will ask you for the drive and directory where you would like to install the library materials. You will also be asked which parts of the materials you want to install. The installation program may be used to install all the materials from CD-ROM or just some part of it, for example one of the libraries.
An uninstall facility is provided. This will remove the product from the user's disk. It will also undo the registry entries made during installation, but will not undo any changes to the autoexec.bat file. If a re-installation is performed, for example to add a component that wasn't originally installed, the uninstall facility will remove only the most recently added files. (However, it will still remove all the registry entries associated with this software.) The uninstaller will not remove files created since the installation was completed (although it will remove original files that have been modified), so the user may have to delete these files to complete the removal.
Four libraries are provided with this implementation:
Note that the library mkl_s.lib is not identical to any of the libraries supplied by Intel in their MKL distribution. It has been adapted for FTN77 by Salford Software and thoroughly tested with the NAG Library (nagmkl.lib) by NAG.
The user should use either nagmkl.lib, mkl_s.lib and kernel32.lib, in order to make use of the Intel MKL BLAS, or just naglib.lib. The installer will be given the choice of whether to install libraries for the Intel MKL BLAS, the NAG BLAS or both.
After installation you should ensure that the software described in Section 3.2 is present and accessible.
The NAG Fortran Library Interface Blocks define the type and arguments of each user-callable NAG Fortran Library routine, using Fortran 90/95 constructs. Although they are not essential to calling the NAG Fortran Library from Fortran 90/95 programs, they will allow a Fortran 95 compiler (such as Salford FTN95/Win32) to check that NAG Fortran Library routines are called correctly.
The interface block files (interface_blocks\*.mod) are supplied in pre-compiled module form. They should be made accessible to the user.
The batch file nagex.bat requires the setting of the environment variable nagfldir. It should be set to the root directory of the NAG materials.
Under Windows 95/98, the autoexec.bat file can be edited to add the environment variable. If the default location is used, add the line
set nagfldir=c:\flw3219ds
This change to the autoexec.bat file can be made by the installation procedure if desired.
Under Windows NT, the environment variable value can be set in the Control Panel | System Properties dialog. If the default location is used, set the variable to
nagfldirand the value to
c:\flw3219ds
The batch file should be made accessible to the user (for example, by copying the file to a directory in the user's path, e.g. c:\utils).
Note that irrespective of which of the two main libraries, naglib.lib and nagmkl.lib, is used, the example program for the routine G02HAF requires the use of the /check compiler option for it to be run successfully.
Note also that when using the Salford FTN95 compiler, the example programs for the undocumented routines F06SAF, F06SBF, F06ZAF and F06ZCF require the use of the /check compiler option. Furthermore, F06SAF and F06SBF require the use of the additional compiler option /suppress_arg_check.
The installation can also be tested by using the nagex.bat batch file, which will copy an example program and its data, compile it, link it with the library and run it. To run an example program, create, for example, the directory c:\test. Make c:\test the current directory, copy the file nagex.bat to it and then give, for example, the command:
nagex c06eafor
nagex -nagblas c06eaf(to link with the library that uses the NAG BLAS (naglib.lib)).
The following material should also be made accessible to users:

examples\source\*.for examples\data\*.dat examples\results\*.res batch\nagex.bat
Note that the example material has been adapted, if necessary, from that supplied in the on-line documentation, so that programs are suitable for execution with this implementation with no further changes (but see Section 4.4.2 for comments about possible differences in results obtained). Making the example material directly available to users provides them with easily adaptable templates for their own problems.
The "example programs" for the routines in the F06 chapter are not typical example programs and they are not in the on-line documentation. They are test programs, which are supplied to sites for use in an installation test of the Library. Some of them take much longer to run than other example programs. Routines which are equivalent to BLAS are tested twice: once when called by their NAG F06 names, and once when called by their BLAS names.
A full on-line version of the NAG Fortran Library Manual is provided in the form of Portable Document Format (PDF) files, and is included with this implementation on the distribution medium.
Abbreviated on-line documentation of the routines is also provided in Windows help file form as part of this implementation.
Printed copies of the NAG Fortran Library Manual are available for purchase; please refer to the NAG documentation order form (available on the NAG websites, see Section 6 (c)) for details of current prices.
The NAG Response Centres are available for general enquiries from all users and also for technical queries from sites with an annually licensed product or support service.
