File   README.CC     how to retrieve CCALL testdata       28 Oct. 1999

             Data for about 20 test structures for DIRDIF
             --------------------------------------------

1. PREPARE FOR STORAGE ( CCALL )

   Make a directory for storage of all structural sub-directories ....
   and make it your working directory.   For instance:
   =====>  mkdir xxxx\xxxx\ccall
   =====>  cd    xxxx\xxxx\ccall
   The actual name 'ccall' is not relevant.

2. TO GET FILES ( diskette or ftp )

   For PC, from diskette:
         Put diskette  'CC'  with test stuctures in drive A:
         Copy all data files from diskette to CCALL :
         -  copy a:\*.*  .

   For any computer, via ftp:
         Get the files via ftp from anonymous ftp ftp.sci.kun.nl :
   =====>  cd pub/dirdif/ccall    # directory for test structures
   =====>  prompt                 # set prompt off
   =====>  bin                    # to get binary files
   =====>  get README.CC          # or just read this file ...... ?
   =====>  ls -l pczip            # list the contents of dir. pczip
         [ or unixzip or unixtar ]  Then decide which file you want:
   either =====>  mget pczip/*    # for MSDOS files  incl. ccpc.zip
   or     =====>  mget unixzip/*  # for unix  files  incl. ccunix.zip
   or     =====>  mget unixtar/*  # for unix, including ccunix.tar.Z
   =====>  quit                   # to quit this ftp session

3. TO RETRIEVE DATA = to unzip or unpack the big file

   For MSDOS PC's, to unzip, enter:
   =====>  pkunzip ccpc           # the file PKUNZIP.EXE is included

   For unix, to unzip, enter:
   either ====>  unzip ccunix     # for SG, sun, etcetera ( ? )
   or     ====>  unzip -L ccunix  # linux or DEC to enforce lower case

   Or for unix, to unpack tar, enter:
   =====> uncompress ccunix.tar.Z # to uncompress, and:
   =====> tar -xf ccunix.tar      # to get individual files.

4. TO RENAME FILES and to store files in individual CCODE derectories

   For MSDOS PC's, just enter:
   =====>  ccrena

   For unix computers, enter:
   =====>  chmod u+x ccrena       # to make the script file executable
   =====>  ccrena                 # to rename and move data files

5. RESULTS

   A large cc.zip file is unzipped.
   For each test structure a sub-directory  CCODE  is made,
        ( for DOS:  CCODE = MONOS, MUEN, ACNORT, TETRAS, JOOST1 ...)
        ( for unix: CCODE = monos, muen, acnort, tetras, joost1 ...)
   and all structural data files are moved to the new directories.

Note:  hard copy documentation about the teststructures is presented
       in the DIRDIF USER's GUIDE .
