5. Hercules Supplied Utilities
5.1 Overview
Several  utility  programs  exist  to  support  the  Hercules  Emulator.  Most  of  them  are  used  when  working  with  
DASD  and  TAPE  files.  Other  utilities  perform  some  special  functions  with  configuration  files.  
All  these  utility  programs  are  pure  line-command  mode  programs  (i.e.  Windows  DOS  or  Unix/Linux  shell).  
They  can  be  called  manually  from  the  command  line  prompt  or  built  into  batch  files.  This  is  generally  the  
preferred  method  due  to  its  greater  flexibility  and  automation  possibilities.  
If  the  Hercules  GUI  (HercGUI)  is  used  the  utilities  can  also  be  called  interactively  via  the  GUI  and  using  a  
graphical  and  menu  driven  interface.
