The OTHERS version of PREPRO2023 comes with FORTRAN source codes, in compressed form - all of the files in the OTHERS package are in DOS format, ready to be used on my Windows/DOS system. 1) Copy OTHERS.tar.gz to your hard drive. First uncompress and untar. After installation you should have a directory named OTHERS that contains 27 files that will you will need to run the executables, and a sub-directory named SOURCES that you will need to create the executsbles; you can delete OTHERS.tar.gz 2) The SOURCES sub-directory contains files to compile and load all of the codes. Execute the batch file for your type of computer, e.g., IBMPC.BAT, LINUX.MAK, MAC.MAK, This could take between 5 and 45 minutes to complete, depending on the speed of your computer. 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) If all of the codes compile you should have a total of 22 executables - 16 in the directory SOURCES, 3 in the directory SOURCES/COMPLOT and 3 in the directory SOURCES/EVALPLOT. Copy or move all 22 executables to the OTHERS base directory - you should then have 49 file in your OTHERS directory. 4) To VERIFY proper installation, it is recommended that after installation you execute a VERIFY.BAT file; see the included VERIFY-IBMPC, MAX, and UNIX as guides to construct a VERIFY.BAT for for computer. 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. 5) If you have any problems notify the Nuclear Data Section, IAEA, Vienna, Austria. services@iaeand.iaea.or.at
