Example how to run history file len-mod.h

• Copy all files of packages FORMS, MODEL and CRT into working directory, e.g., sw3d. For some programs you will need few subroutines of Numerical Recipes.
• Go to working directory sw3d. Edit file f.pl. Uncomment and modify commands for your compiler and comment line with 'die "Uncomment and modify ...' (line 46).
• Compile and link programs of packages FORMS, MODEL and CRT using the commands:
  perl fforms.pl
  perl fmod.pl
  perl fcrt.pl
  These perl scripts compile and link all executable programs of the packages (only few are necessary to run len-mod.h history file). To compile and link single program, e.g., crt.for, use the command:
  perl f.pl crt
  If perl interpreter is not installed on your computer, ask your system administrator or see www.perl.org.
• Copy history file len-mod.h together with all other files from subdirectory len of package DATA into working directory sw3d.
• Enter the command:
  perl go.pl len-mod.h
  to run the history file.

  Note that instead of copying all the files of directory len into working directory, you may alternatively set the path variable $SW3D, copy just the history file len-mod.h into working directory, and run it. If the path variable $SW3D is set correctly, all files required for the computation should be checked and copied into working directory sw3d automatically by Perl script chk.pl when running the history file. To set path to the root directory of the SW3D software in global variable $SW3D, edit file go.pl. You can specify, e.g., $SW3D='/cdrom/web/software/sw3dcd??/' (the two question marks ?? stay for the number of the SW3D-CD you wish to use) if the SW3D-CD disk is in your CDROM drive mounted to the directory /cdrom, or $SW3D='/home/username/sw3d-cd/web/software/sw3dcd??/' if the SW3D-CD disk is copied on your harddisk into the directory /home/username/sw3d-cd.
