The IBM/Windows version of PREPRO2018 comes with executable codes, in compressed form.
 
1) Copy IBMPC.tar.gz to your hard drive. First uncompress and untar - we 
   recommend you use 7-zip, which is available FREE on the internet, or any 
   similar uncompression code that you may have. After installation you should 
   have a directory named PREPRO18 that contains 43 files; you can then delete 
   IBMPC.tar.gz
 
2) To VERIFY proper installation, it is recommended that after installation 
   you execute VERIFY.BAT (Be sure to type the entire name, VERIFY.BAT,
   to avoid a conflict wth the DOS verify command). This is a batch file that 
   will run the codes in sequence.
 
3) 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.

   If plots are displayed before the batch file (VERIFY.BAT) finishes, the entire
   system has been verified and is ready to use. If you do not obtain plots, there
   was an ERROR during installation; in this case 4) below.
 
4) If you have any problems notify the Nuclear Data Section, IAEA, Vienna, Austria.
