The VMS version of PREPRO2010 comes with OSX executables codes, 
in compressed form.
 
1) Copy VMS.tar.gz to your hard copy and uncompress and untar it.
     After installation you should have a single directory named PREPRO10
     that contains 42 files; you can then delete VMS.tar.gz.
 
2) To VERIFY proper installation, it is recommended that after installation you 
     execute verify.com. 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 % are acceptable; larger differences indicate an installation 
    problem.

   If plots are displayed before the batch file (VERIFY.BAT) finished, 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.
