  A.  TEXT FILES

        1)  READ.ME  -  General information and         ASCII         1
                        execution instructions.
                        Users are advised to read
                        before proceeding.

        2)  AHP1.F   -  FORTRAN source files for          |           4
            AHP2.F      the UNIX based workstation
            AHP3.F      version (can handle up to
            AHP4.F      121 groups).


  B.  COMPRESSED, SELF-UNPACKING FILES

        1)  ANISN_PC.EXE - Contains the executable      Binary       21 **
            module and all files required to run
            ANISN/PC, three sample problems, an
            interactive input generator (APE32),
            and a library editing program LMOD
            for handling the ISOTXS cross sections.

     **  Denotes the number of reconstructed files; refer to
         READ.ME for DOS file name and contents.

  C.  Auxiliary programs for cross-section processing.
         ANTOPC.FOR - source to convert ANISN-formatted     ASCII     1
         cross sections to a format accepted by ANISN/PC.
         ANTOPC.EXE - executable                            BINARY    1
         ANTOAPE.FOR - source to convert ANISN-formatted    ASCII     1
         cross sections to a format accepted by APE.
         (Does not use the repeat option.)
         ANTOAPE.EXE - executable                           BINARY    1

     NOTES:
     This edition of ANISN-PC is contained on one high-density (1.2Mb)
     diskette.  Files for the PC version have been compressed using
     the PKware data compression utilities.  Only the ANISN FORTRAN
     source is provided for the UNIX based workstation version.

     Sample problem 3 requires IBUF = 1184. (see READ.ME)

     Installation -   Copy the .EXE file to a subdirectory on your hard
                      disk and execute it.

     June 1993
     There is an error in Subroutine WATE in file ANISN4.FOR.  It is a
     problem with cross section weighting and removing upscatter cross
     sections while retaining multiple thermal groups.  The correction is
     to add the following 2 lines where indicated below.

      CXF(IHST,IIG,NNN)=CXF(IHST,IIG,NNN) + CXF(IH,IIG,NNN)
      CXF(IHST,  K,NNN)=CXF(IHST,  K,NNN) + CXF(IH,IIG,NNN)
      CXF(I06 ,  K,NNN)=CXF(I06 ,  K,NNN) - CXF(IH,IIG,NNN)
