  3. ; Switch Directory - DOS   Copyright (c) Stephen M. Falatko, 1987, 1988        ;
  4. ;                                                                              ;
  5. ;     Switch  Directory  -  DOS  (SD)  is  a utility that allows easy          ;
  6. ;     switching between subdirectories and  drives with  a minimum of          ;
  7. ;     typing.   SD has  been designed  to replace  the DOS CD command          ;
  8. ;     while providing enhancements to the CD command.   SD allows you          ;
  9. ;     to  specify  a  specific  subdirectory  name,  a combination of          ;
  10. ;     subdirectory names  and  search  switches  or  a  complete path          ;
  11. ;     specifier.   All features  of SD work  across disk  drives.  If          ;
  12. ;     you have made a mistake, hitting Ctrl-Brk while SD is searching          ;
  13. ;     will   break you out of SD and put you back in the subdirectory          ;
  14. ;     you started in.                                                          ;

  16. ;     Switch Directory - DOS 1.0 is descended from SD version 3.4 and          ;
  17. ;     its predecessors.   The  improvement in SD is that SD - DOS can          ;
  18. ;     attach  itself  to  DOS  and  provide  the  same  functionality          ;
  19. ;     previously only  available with  SD in combination with PCED or          ;
  20. ;     CED.  For users of PCED or CED, an enhanced  version of  SD 3.4          ;
  21. ;     is available called Switch Directory - CED.                              ;
