Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A CICS application has a help facility, which is invoked by
  hitting PF1.  After upgrading maintenance the user cannot invoke
  the help panel.   The following is seen in the NVAS log.

  ****************************************************************
  * RECOMMENDATION: APPLY THE PTF FIXING THIS APAR               *
  ****************************************************************
  In the 3472-4 InfoWindow real terminal environment, the PF1 key
  depressing for help at the end of an autologon to a CICS appl
  does not work; the same procedure works correctly in the 3192G
  real term env.
  At problem time NVAS changes the no-AID x60, received from the
  3472-4 real term, with the x88 aid (structured field) and
  forwards this to the appl; the correct x60 data stream is
  forwarded to the appl in the 3192G case.
  The wrong case arises when NVAS misunderstands a previous
  structured field query reply stored in the server term virtual
  terminal control block with the no-AID just received from the
  real term, then it replaces the data stream and forwards it
  incorrectly.
  

Problem conclusion

• Now NVAS checks for the no-AID x60 data stream when in the
  server term virtual term control block there is stored a
  previous x88 query reply structured field, and avoids to fall
  in the previous dangerous update, issuing a better check about
  the replacement aid routine.
