OA58386: CURSOR POSITIONING WITH 3270 DATA STREAMS USING 12 BIT ADDRESSING

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When generating 3270 Data Streams to position the cursor on the
  screen, Rexx/CICS is always using 12 bit addressing in the Send
  Buffer Address (SBA) instruction, rather than switching to 14
  bit, and consequently can function if the required position is
  within the first 4K of the screen. Positions over this are
  either effectively "wrapping" within this section or resulting
  in invalid commands being sent to the screen.
  
  This is an issue with large screen sizes, eg 62X160, as the
  size exceeds 4K.

  ****************************************************************
  In the reported problem, the customer attempted to run Rexx for
  CICS on a 62 x 160 screen.  A screen of this size has 9920
  character positions.  CICS Rexx code builds 3270 datastreams
  using 12 bit addresses but these are limited to a maximum of
  4096 positions which is insufficient for a 62 x 160 screen.
  A PROG752 error occurred.  The problem may also present as text
  appearing in unexpected positions, or a REX1 abend.

Problem conclusion

• CICS Rexx code has been modified to address the reported
  problem.
