   ZCRCK  is  a ZCPR3-compatible version of Sigi Kluger's  NCRCK1,  which  was 
designed  to  replace  the CRCK and CHEK programs found  on  RCPM  systems  by 
combining both features.   ZCRCK operates much the same as NCRCK1, except that 
it fully understands the ZCPR3 environment and it obeys - and displays - named 
directory and DU:  references.   All patching has been eliminated,  MAXDRV and 
MAXUSER are now provided by ENV values,  display of $SYS files is now a wheel-
controlled  function.   NCRCK split its hex display in byte-size pieces (5000h 
became  50 00);  ZCRCK's display is more conventional,  to conform with  NULU, 
PPIP, etc.

   Syntax   ZCRCK [du: or dir:]afn [[/]Options]

  Options   L   <-- output listing to LST: device
            D   <-- output listing to file CRC.CRC

   ZCRCK  will  identify  itself,  print a header line and  then  process  all 
matching files.   CRC values for the selected files will  be displayed.   Both 
"CHEK" and "CRCK" values are shown.

 ZCRCK Notes 

   a. Version 1.3 (12/11/89) adds  option  to send output to disk file.   Some
      minor bugs fixed.

   b. Version 1.2 (02/20/88) uses faster table-driven  CRC3xxxx routines  from
      SYSLIB4, includes type-3 safety header, and adds a few cosmetic touches.

   c. Version 1.1 (05/13/87) includes a  printer output option and makes ZCRCK 
      a Z33 type 3 COM file.  It will not run on an 8080 or 8085.
