 ------------------------------------------------------------------------

  INDEXINP - An interactive program to generate automatically the input
             data files for the indexing programs DICVOL, ITO, and TREOR.

 ------------------------------------------------------------------------  


                         OPERATIONAL DETAILS


     INDEXINP prompts the user for all the necessary data, and then
  generates the three files "dicvol91.inp", "ito.inp" and "treor90.inp",
  which can be used directly with DICVOL91, ITO and TREOR90.

     2theta (d-spacing) values can be input either interactively or via
  a file whose name can be chosen by the user.  If the user chooses the
  latter option, then the data file should simply contain one entry 
  (2theta or d-spacing) per line and nothing else.  An example is the
  file "cim.dat", for the cimetidine data set, in the current directory. 
  The entries need not be in numerical order, since INDEXINP will sort
  them appropriately before inserting them in the indexing input files.
  If the user wishes to input 2theta (d-spacing) values via a file, but
  has not created this file before running INDEXINP, then the program
  allows the user to exit program and create the data file before          
  returning to INDEXINP.

     All of the required parameters come with default values, which are
  indicated in the prompt.  To select the default value for any 
  parameter the user should simply type "RETURN" following the prompt.


  COMMAND LINE : The user should type "indexinp" to invoke the program.
