   To illustrate:   
      
   VMS Tech Demo 21 - data export with Spring Batch   
      https://www.vajhoej.dk/arne/articles/vmstd21.html   
      
   VMS Tech Demo 22 - data import with Spring Batch   
      https://www.vajhoej.dk/arne/articles/vmstd22.html   
      
   Which are repeats of:   
      
   VMS Tech Demo 18 - getting data out of VMS   
      https://www.vajhoej.dk/arne/articles/vmstd18.html   
      
   VMS Tech Demo 19 - getting data into VMS   
      https://www.vajhoej.dk/arne/articles/vmstd19.html   
      
   but with the custom Groovy/Jython code replaced with   
   Spring Batch and XML config - in reality coding in   
   XML instead of Groovy/Jython.   
      
   For index-sequential file it is using two files, so it   
   is the MultiIsamItemReader/Writer being used.
