  FUNCTION = Provide mapping for autoinstall work element components.
  
  The DSECT is used solely within the ZCP DOMAIN.
  
  There are as many WE's as there are autoinstall requests
  in progress.
  
  The WE is used to store the CINIT_RU or BIND so that the
  logon may be attempted by DFHZATA.
  
  If the WE contains a TCTTE address then this is a
  Postponed autoinstall work elemment (PWE), created by
  DFHZLGX when there is a LOGON for a TCTTE which is
  currently being deleted.
  
  If the WE has TCTTECWE set then it is a Autoin-
  stall Work Element used to autoinstall a
  console and to sign-off or sign-on a known
  console automatically.
  
  LIFETIME = The WE is created by a GETMAIN issued by DFHZLGX
  (LOGON-EXIT) or DFHZSCX (SCIP exit) or DFHZCNA
  (Console Input) when an unknown terminal or
  console or APPC device attempts to LOGON or BIND
  or an unknown console issues an MVS MODIFY. It
  is also created if a known console needs to be
  signed-off or signed-on automatically.
  It is also created for a known terminal subject to
  certain restrictions. The WE is freed by DFHZNCA
  after DFHZNEP is driven for the OPNDST contition
  TWAEC=TCSOPSIN or prior to DFHZNEP being driven for
  a CLSDST contition TWAEC=TCZCLSIN.
  
  The WE is freed by DFHZATA when the request has been
  processed.
  
  STORAGE CLASS = USER(OS - SUBPOOL 1)
  
  LOCATION = For unknown terminals, each WE is chained off the
  previous one and the first one is anchored from
  TCTVANWE in the TCT prefix. After the TCTTE is
  built by DFHZATA for autoinstall-eligible devices,
  the WE address is saved in TCTEAWEA. For known
  terminals, DFHZLGX updates TCTEAWEA.
