   SHOW  is  the ZCPR3 environment display utility.   SHOW generates  numerous 
displays  which include:   details of the ZCPR3 environment  descriptor,  what 
system facilities are available, and the status of these facilities.

   SHOW  can be invoked as an error handler,  in which case its error  handler 
display  can  give the command line status and its  other  displays,  such  as 
memory examine, may prove useful to analyze the state of the ZCPR3 system.

   SHOW  is  screen-oriented  and will not function correctly  without  proper 
Z3TCAP support.

SHOW Notes:

   a. Vers 1.4  fixes error in display  of status  of  certain  flags  (QUIET,
      FORMFEED capability of LST device),  updates reference to Z33DEFN.LIB to 
      Z34DEFN.LIB.

   b. Vers 1.3 supports ZCPR34 and the extended  ENV module with drive vector,
      single CRT/PRT,  and address/size of CPR,  DOS,  BIOS.   Safety code was
      added to  check for Z-System  and adequate TCAP.   Also supports Z3PLUS.

   c. Vers 1.1 supports  the  new  features  of  ZCPR 3.3.   Almost all of the
      configuration options for  ZCPR 3.3  are displayed in three new screens.
      Resident  command displays for the RCP,  FCP, and  CPR indicate by using
      lowercase which  commands  are wheel-restricted.  For the FCP,  not only
      are the commands shown, but all the resident options are listed as well.
      For Z33FCP, additional information about automatic chaining to IF.COM is
      also presented.  The  memory-display  function includes column  headers,
      and an elementary memory  poking function  has  been added.   Failure to 
      provide input to a prompt returns one to the command prompt.
