VM66340: SET FILE MASK CCW UNDER Z/VSE TRANSLATED INCORRECTLY

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Z/VM incorrectly translates a Set File Mask (SFM) when con-
  verting to a NO-OP command.  The SFM is part of the Define
  Extent (DX) CCW string of their translated ECKD program.  Z/VM
  erroneously copies the original CCW flags including IDA and CCW
  data address flags from the Guest Z/VSE channel program.  This
  causes a channel program check.

  ****************************************************************
  A z/VSE channel program containing a Set File Mask encounters
  a channel program check.  The reason is that CP incorrectly
  handles the Set File Mask (SFM) CCW flags when converting
  to a NO-OP command.  The SFM is part of the Define Extent
  CCW string of their translated ECKD program.  Z/VM erroneously
  copies the original CCW flags including IDA and CCW data
  address flags from the Guest Z/VSE channel program.  This
  causes a channel program check.
  

Problem conclusion

• CP's translation code has been changed to properly translate
  a Guest's SFM CCW when converting to a NOP CCW.
