The UNIX version of PREPRO2012 comes with FORTRAN
source codes, in compressed form.

1) Copy UNIX.tar.gz to your hard drive. First uncompress
     and untar. After installation you should have a directory 
     named PREPRO12 that contains all of the files; you can 
     delete UNIX.tar.gz 

2) This system comes with batch files to compile and
     load all of the codes, and clean up the final form
     of the PREPRO directory. Execute the batch file
     for your type of computer, e.g., SUN.BAT, SGI.BAT,
     CRAY.BAT, etc. This could take between 5 and 45
     minutes to complete.
 
   If the codes EVALPLOT and COMPLOT fail to compile and
   load then you may need to change the path in the
   Makefile to the directory that contains your X-Windows
   routines, i.e. /usr/lib/X11
 
3) To VERIFY proper installation, it is recommended
   that after installation you execute VERIFY.BAT This
   is a batch file that will run the codes in sequence.
   The final two codes will display the calculated
   cross sections (EVALPLOT), and compare the results
   you calculated to a standard set of results (COMPLOT).
   Difference of about 1 % to 2% are acceptable; larger
   differences indicate an installation problem.
 
4) If you have any problems notify the Nuclear Data
   Section, IAEA, Vienna, Austria.
