To use the INSTALL program, place the original diskette into an appropriate drive (e.g., A:) and type A:INSTALL followed by the <Enter> key. Then, follow the directions as indicated. The Numerical Recipes routines consist of more than 600 individual files (including both the recipes and the sample driver routines). Fully unpacked, this large number of files requires excessive disk space, and degrades the performance of programs that scan the full directory tree. Furthermore, few users ever want to use more than a small number of the routines at any one time. We therefore supply the routines in the form of a small number of compressed archive files, and a special dearchiving program called NRCOPY. When properly installed, NRCOPY becomes a command that is available from any working directory. On request, it creates a copy of any desired routine. You can use, modify, or delete this copy: a fresh copy can always be obtained by the NRCOPY command. more... Here is an overview of the INSTALL process: (If you have already completed the installation, you might wish to verify that you went through all these steps.) 1. You are asked to select a drive and subdirectory that are in your DOS path. (Your current DOS path is displayed.) You can choose an existing subdirectory or a new one. The archive files must be somewhere in your path so that the NRCOPY command is able to find them. 2. You are asked to enter your name, or the name of the person or organization to whom the diskette is licensed. This name is used to construct a short license validation file with a name like NR20KEY.AR. This file must be kept in the same directory as the archive files, otherwise NRCOPY will not be able to work. 3. The following files are copied to the subdirectory that you chose: the archives NRC20REC.AR, NRC20EXA.AR, NRC20OTH.AR, NRK20REC.AR, NRK20EXA.AR, and the executable commands NRCOPY.EXE and NRHELP.COM (this file). The validation file NR20KEY.AR is also put in place. 4. If (and only if) you requested that your AUTOEXEC.BAT file be modified to include your chosen subdirectory in your DOS path, this modification is made. When the INSTALL process is complete, and after you have rebooted your machine so that the PATH is reset, you will be able to use the commands NRCOPY and NRHELP from any working directory. Press F4 now to get instructions for using NRCOPY. (For short instructions at any time, just type NRCOPY at a DOS prompt.) { How to INSTALL the Numerical Recipes archives} { ANSI C vs. traditional K&R C files} About ANSI C and K&R C There are two dialects of the C language commonly in use. The older one is called Kernighan and Ritchie (K&R) C or "traditional" C. The newer one, which is fast replacing K&R C, is called ANSI C. The program listings in the Numerical Recipes books are all in ANSI C. We recommend that you use ANSI C if at all possible. Microsoft C/C++ version 7.0 and later is fully ANSI C compatible, as are current versions of Borland C++ and Turbo C. If you do use ANSI C, you should use the "C", not the "KRC" archives on this diskette. Press F4 for information on how to use the NRCOPY command to specify which archives are used. You must also be aware that the header files nr.h and nrutil.h, and the utility files nrutil.c and complex.c, all supplied in the "OTHER" archive, incorporate both ANSI C and K&R C versions. To make the ANSI version active, you must be sure that one of the following macros is defined at compile time: ANSI, __STDC__, NRANSI. Most ANSI compilers will automatically define __STDC__ if you specify that you want ANSI C conformity. In Microsoft C, the command line switch for this is "/Za". In Borland C, the switch is "-A". These and most other compilers also allow you to define macros directly on the command line. In Microsoft C, you would define ANSI by the command line switch "/DANSI". In Borland C, the switch would be "-DANSI". Consult your compiler documentation for more details. As further backup, all the ANSI C files on this diskette themselves internally #define NRANSI before accessing the header files nr.h or nrutil.h. If you run into trouble, it is probably because you have referenced one of these header files in your own program (or compiled nrutil.c or complex.c) without the required #define NRANSI or command line switch. If you have a traditional or K&R C compiler, be sure to unpack your files from the "KRC" archives. You need not (in fact, must not) define any special macros at compile time. Press F5 for sample command lines to unpack, compile, and run programs from this diskette. { ANSI C vs. traditional K&R C files} { How to use NRCOPY (accessing the files)} All About NRCOPY The NRCOPY command can be executed at any DOS prompt, from any working directory. It locates any desired Numerical Recipes files in the archives, and makes useable copies in the directory of your choice. It can also be used to list the contents of an archive (names of the files) or to view on the screen, rather than copy, selected files. The complete syntax of the command is: NRCOPY C|KRC|FOR RECIPES|EXAMPLES|OTHER [files] [LIST|VIEW|TO path] Here, arguments with bars, like "a|b|c", signify that you must choose exactly one of a,b, or c, while square brackets like "[ ]" signify that an argument is optional. All arguments are case insensitive (you can type them in upper case, lower case or any combination). The keywords C, KRC, FOR, RECIPES, EXAMPLES, and OTHER, can be abbreviated down to a single letter, C, K, F, R, E, and O, respectively. The action of the command is as follows: The C, K&R C, or FORTRAN archive (depending on the first argument) that contains RECIPES, EXAMPLES or OTHER files (depending on the second argument) is opened. (Only C and K
