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 (including
Salford FTN95 and Digital Visual Fortran version 5)
Other language compilers with which this implementation may be used include:
C compiler: Microsoft Visual C++ version 4.2 and above Visual Basic: Microsoft Visual Basic Version 4 and above VBA: within Microsoft Office 7 and aboveThe DLLs may also be used from other systems that can exploit Microsoft-compatible DLLs, for example Delphi, PowerBuilder and C++ Builder.
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: /MD /compile /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)
The Dynamic Link Libraries were linked with the following options:
/DLL /VERSION:19.0 /COMMENT:"NAG Copyright 2000" /OUT:dllname.DLL routine.OBJ /EXPORT:_routine@n /EXPORT:routine=_routine@n /EXPORT:_routine=_routine@nwhere
/DLL specifies that a DLL is required /VERSION: puts a version number in the header of the DLL /COMMENT: inserts a comment string into the header of the DLL /OUT: specifies the base name to be used for the DLL /EXPORT: names the function to be exportedHere routine is the NAG routine name. Note that each routine is exported using three different forms of its name: the first (termed the decorated name) consists of a leading underscore, followed by the routine name, followed in turn by an @ and an integer - the integer contains information about the number and type of parameters; the second is the (undecorated) NAG name; the third is the NAG name with a prefixed underscore. The names are in capital letters and must be used in that form on case-sensitive systems. The three forms exported are appropriate for usage of the DLLs in different contexts.
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 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.
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 directory path for the DLLs should be specified in the PATH environment
variable so that they may be located at run time. 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.
It is also recommended that you add the library files 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 4.2 and 4.13 of the Users' Note).
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:\fldll194z\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 "DLLZ," \
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:\fldll194z\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.
runexallIf this runs successfully, it should report
FC: no differences encounteredin turn for each of the 22 tests (one for each DLL). The outcome may also be investigated by examining the file look.lis.
If the directory containing the DLLs is not on the current path, or the DLLs are not accessible for any other reason, the tests will fail.
(The file e04ndf.opt in the directory tests contains option settings for the test e04ndf.)
All the material listed in Section 3.2 except this document, the Installer's Note (in.html), should be made accessible to users.
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.
