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. In particular, users must not have free access to the text of the library routines. 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: all systems in the VAX range operating system: VAX/VMS V5.5 or compatible Fortran compiler: VAX Fortran (with the G_FLOATING qualifier)
User programs must be compiled with the G_FLOATING qualifier.
For information about implementations of the NAG Fortran Library for use on other computer systems please contact NAG.
This implementation was produced at the Computing Centre of Cardiff University on the computing system detailed below:
hardware: DEC VAX-4200 operating system: VAX/VMS V5.5-2 Fortran compiler: VAX FORTRAN V5.9-173 (with the G_FLOATING qualifier) Assembler: VAX MACRO V5.4-3 compiler options: /OPTIMIZE /CHECK=(NOBOUNDS,OVERFLOW,NOUNDERFLOW)
The entire Fortran Library, Mark 19, was compiled with full optimization.
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 Manual) only.
For further details, refer to other documentation supplied or contact NAG (see Section 6).

$ BACKUP DKA400:[000000]INSTALLG.BCK/SAVE_SET []

This command procedure also gives you the option of

$ SET PROTECTION=W:RE SYS$COMMON:[SYSLIB]NAGG$LIBRARY.OLB
$ DEFINE/JOB LNK$LIBRARY SYS$COMMON:[SYSLIB]NAGG$LIBRARY.OLBIf the logical name LNK$LIBRARY is already in use then the first empty logical name from the following list should be used:
LNK$LIBRARY_1, LNK$LIBRARY_2, ....., LNK$LIBRARY_nIf the user has sufficient privileges, the JOB qualifier may be replaced by the GROUP or the SYSTEM qualifiers. N.B. The association should be placed in the appropriate initialising command file, for example SYLOGICALS.COM for the /SYSTEM qualifier or the LOGIN.COM of authorised users. This will ensure that the library will still be linked automatically even if the system has to be re-booted.
Alternatively you can set the library up as you wish, for example by linking explicitly with the library in each LINK command.
$ MOUNT/MEDIA=CDROM/UNDEFINED_FAT=fixed:none:8192 DKA400: FLDVV19DG $ BACKUP DKA400:[000000]INSTALLG.BCK/SAVE_SET [] $ BACKUP DKA400:[000000]LIBRARYG.BCK/SAVE_SET [] $ DISMOUNT DKA400:
$ @NAGGSHAREand then copy the files required to use the shareable library to an appropriate directory, e.g.
$ COPY NAGG$SHARE.OLB SYS$COMMON:[SYSLIB]NAGG$SHARE.OLB $ COPY NAGG$SHARE.EXE SYS$COMMON:[SYSLIB]NAGG$SHARE.EXEThe supplied file NAGG$SHARE.MAR should be in the current directory when this procedure is used, if compatibility with previous shared versions and compatibility between sites is to be assured. After building the shared version for the first time, the resulting NAGG$SHARE.MAR should be kept and the newest version used for each subsequent rebuild.
$ SET PROTECTION=W:RE SYS$COMMON:[SYSLIB]NAGG$*.*
$ DEFINE/JOB NAGG$SHARE SYS$COMMON:[SYSLIB]NAGG$SHARE.EXEThe library file NAGG$SHARE.OLB should be associated with a LNK$LIBRARY name:
$ DEFINE/JOB LNK$LIBRARY SYS$COMMON:[SYSLIB]NAGG$SHARE.OLBThe library can have a higher LNK$LIBRARY name if required. If the user has sufficient privileges, the JOB qualifier may be replaced by the GROUP or the SYSTEM qualifiers. N.B. These associations should be placed in the appropriate initialising command file, for example SYLOGICALS.COM for the /SYSTEM qualifier or the LOGIN.COM of authorised users. This will ensure that the library will still be linked automatically even if the system has to be re-booted.
The following material should also be made accessible to users:

NAGG$LIBRARY.OLB from the save set LIBRARYG.BCK (or the shareable library created from it)example program material:
*.FOR from the save set EXPTG.BCK *.DAT from the save set EXPDG.BCK *.RES from the save set EXPRG.BCK
Note that the example material has been adapted, if necessary, from that printed in the NAG Fortran Library Manual, 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 Library Manual. 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 available in the form of Portable Document Format (PDF) files. Please contact NAG if you are interested in this.
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.
The Response Centres are open during office hours, but contact is possible by fax, email and phone (answering machine) at all times.
When contacting a Response Centre please quote your NAG site reference and NAG product code (in this case FLDVV19DG).
The NAG websites are an information service providing items of interest to users and prospective users of NAG products and services. The information is reviewed and updated regularly and includes implementation availability, descriptions of products, downloadable software, product documentation and technical reports.
