This tape contains the source FORTRAN code for the TABLES program (V 2.0)
The executable file is also here, and should be able to run on
your VAX without any problem.  If you need to recompile and/or
relink, here is how to do it:

   $ FORT TABLES      !PARAMS.INC is required.  It's on the tape, too
   $ LINK TABLES

To run the program just type RUN TABLES.  It will prompt for all
necessary information.  The only required input file is a space
group file.  76 example files (enantiomorphic space groups) are on this tape.
There will be two output files (default CELL.PIX and SYMOPS.PIX)
which can be displayed using GRAMPS.  Use the GRAMPS GET command.

TABLES will optionally read a motif file in one of three formats
and output a file in Cambridge Crystal file format.  This file
cannot be displayed directly using GRAMPS.  There are two sample
input files, one in MSF format (local to Abbott) and the other
in Cambridge format.  These files are called 1NAL.MSF and
1NAL.CDB.  They are there as examples for you.  The input file
you use must be in orthogonal coords.
You may also output a GRAMPS .PIX file containing the crystal packing
of the motif for that space group.

There are files which can be use to verify that TABLES is running correctly
at your site.  The file EXAM1.COM will run TABLES
to produce four output files: CELL.PIX, SYMOPS.PIX; SPG2.PIX 
and SPG2.CRY (packing files). 
There will also appear a scratch file  (SPG1.CRY)
wich is a temporary file for TABLES containing the cell constants,
the symmetry operators and the fractional coordinates of the motif in
the asymmetric unit. This file can be used directly as input in the updated
version of TABLES (named TABLAS; see below).  These files should be
identicals to the ones included in the export tape having the corresponding
names.  SAMPLE.RUN is output from my run of EXAM1.COM. If your files do not
exactly compare with the files on the tape, then TABLES is not running
correctly at your site.
      ***************************************************
PLEASE NOTE THAT THE CORRECT SPACE GROUP FOR 1NAL SHOULD BE P21/C.
HOWEVER, SINCE THE EXPORT TAPE ONLY PROVIDES DATA FILES FOR THE 
ENANTIOMORPHIC SPACE GROUPS THIS PARTICULAR ONE IS NOT AVAILABLE AND
THE TEST IS RUN WITH P21 (B-CHOSEN AS THE UNIQUE AXIS). YOU COULD
EASILY SET UP YOUR OWN DATA FILE FOR P21/C WITH VERY LITTLE EFFORT.  
      **************************************************
Also available in this export tape is version 2.1 of TABLES, here called
TABLAS to avoid confusion.  It is completely
analogous to TABLES except for one thing. There is a path in the program
by which one can skip the generation of the CELL and SYMOPS files and go
directly to generating the crystal packing from a Cambridge Data Bank
file (in fractional coordinates) containing the cell constants and the
symmetry operators. This program, however, does not output GRAMPS 
compatible (.PIX) files.
The files ALALA.MSF and ALALA.CRY can be used to test this version
(VER 2.1) of the program and the alternative pathway in the following
manner. Use directly the file ALALA.CRY as input to TABLAS to generate
the crystal packing. The output should be identical (assuming you
chose identical options for the packing) to the one you would obtain
by running ALALA.MSF as a motif after generating the AACELL.MSF and
AAOPS.MSF files. Example output for the two latter files are provided
in I4CEL.MSF and I4OPS.MSF. Except for the order of the symmetry
operators and the number of the atoms (which is irrelevant) the scratch
file AASPG1.CRY, produced by the full run of TABLAS, should be identical
to the file provided ALALA.CRY.
You can use the file EXAM2.COM to execute TABLAS generate AACEL.MSF (cell)
AAOPS.MSF (operators), AASPG1.CRY (essentially identical to ALALA.CRY) and
AASPG2.CRY. This second file should compare exactly with AAXTAL.CRY when
using the option that generates only the unit cell and allowing for
the molecules outside the cell to be brought in.
******************************************************************************************
Two simple motifs (a triangle and a number seven) are also provided in this
tape to test complex packing in high symmetry space groups. They are in MSF
format. Also provided are the coordinates (in both .MSF  and .CDB format)
of a natural compound name Ginkgolide (Space Group P1) Acta Cryst. (1986)
C42,1759-1762.
********************************************************************************
Based on this export tape you can make your own choice as to how to
display the three separate image files in your computer graphics
environment. Use TABLES and display the output files with GRAMPS or
use TABLAS and adapt the output files to your own graphics 
display system (s).
********************************************************************************
 Let's try to visualize and manipulate the space group
information of the TABLES in stereo and in three dimensions.
