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: 32-bit Intel systems and compatibles operating system: Windows 95/98 or Windows NT Fortran compiler: Compaq Visual Fortran version 6.0 and compatible
Although this implementation is a static library implementation, it can be called from Microsoft Visual C++ versions 5.x and 6.x (see Section 3.7 of the Users' Note). To interface with Microsoft Visual Basic, Excel and other Windows software, the NAG DLL implementation is more appropriate.
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: Dell OptiPlex GX1 operating system: Windows NT 4.0 Fortran compiler: Compaq Visual Fortran version 6.1 compiler options: /compile /nodebug /bintext:"NAG Copyright 2000" utilities: Intel MKL library, version 3.2
The entire NAG Fortran Library, Mark 19, was compiled with full optimization (/optimize:5), except for the following routines which had to be compiled at lesser optimization levels:
E02AHZT.FOR (/optimize:4) E04GZFT.FOR (/optimize:0)
This library has been tested using the Basic Linear Algebra Subprograms (BLAS) provided in the Intel MKL Library, version 3.2 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)).
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 the library.
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.
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 constructs. Although they are not essential to calling the NAG Fortran Library from Fortran 90 programs, they will allow a Fortran 90 compiler (such as the Compaq Visual Fortran compiler) 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. If you are using a different version of the Compaq Visual Fortran compiler from that given in Section 2.1, it may be necessary to recompile the interface blocks before making them available.
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:\flw3219dd
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:\flw3219dd
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).
It is recommended that you add the library and module files paths to the LIB and INCLUDE environment variables respectively. This will simplify linking with the library and using the interface blocks on the command line (see Sections 3.1 and 3.6 of the Users' Note). Under Windows 95/98, this requires a change to the autoexec.bat file which can be made by the installation procedure; under Windows NT, the environment variables can be set in the Control Panel | System Properties dialog.
If your machine has more than one processor, then it is recommended that you set the environment variable mkl_nprocs to the number of available processors, e.g.
set mkl_nprocs=2This will enable the Intel MKL BLAS to make use of the extra processor(s) and will thus speed up the computation of many of the NAG library routines.
For the NAG Fortran Library you will be provided with an uncounted license key for use on a specific machine. This type of license is bound to a PC through the volume serial number of the PC's Windows drive (where the Windows directory is installed); this will normally be the C drive. To obtain the volume serial number, type "vol" in an MS-DOS window while accessing the appropriate drive.
To obtain the appropriate license key, contact the NAG Response Centre quoting the volume serial number of your machine and specify that you wish to obtain a PC license for the NAG Fortran Library. You will then receive your license information, usually by email or fax.
The information that you receive from NAG contains a FEATURE line describing the product being licensed. This line has to be inserted into a license file (say c:\flw3219dd\license.dat). The license file is a text file (usually created using a text editor, for example EDIT) and the FEATURE line must occupy a single record; none of the characters in the FEATURE line may be modified or the license will be invalid.
The format of the FEATURE line of a NAG Fortran Library license is as follows:
FEATURE NAG_FL NAG 19.000 01-jan-0000 0 2CE45AEB6D064ACEBE61 "W32D," \
DISK_SERIAL_NUM=b0d85e5b
This enables the use of version 19.0 of the application NAG_FL with no time limit on the system with the specified volume serial number. Note that the line is continued by escaping the newline character with '\'.
To activate the license, the location of this file must be made known to the NAG Fortran Library. This is done by setting the environment variable LM_LICENSE_FILE to the full pathname of the license file. Using the license file described above as an example, under Windows 95/98 this can be done by adding the line
set LM_LICENSE_FILE=c:\flw3219dd\license.datto the autoexec.bat file and then rebooting the system.
Under Windows NT, LM_LICENSE_FILE can be added as a system or user environment variable using the Control Panel | System Properties dialog.
The installation can also be tested using the script nagex.bat, 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 c06eaf
The following material should also be made accessible to users:
documentation files:
doc\essint doc\summary doc\news doc\replaced doc\calls doc\called doc\blas_lapack_to_nag doc\nag_to_blas_lapack doc\mk19.hlpcompiled library:

headers\nagmk19.h headers\nagmk19.hxx headers\techdoc.html headers\mk19\*.c
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 4.5.2 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.
