Skip, Thanks for sharing this. I used this to check my systems that have the PTF on them, against those that have not yet been IPLed. I didn’t press IBM for this in the ETR I had opened on this, but should have.

To see your vulnerability, use IPCS ACTIVE or Omegamon MLST or Mainview (???) to display data currently in the UCCB control block at +10: 10?+220?+3C?+10 Before the PTF, you will see something like CFA83DBE 87F18D69 , which is a copy of the system clock at the last IPL. The problem is that on December 15, this data turns to D0000000 00000000 . With this clock value, the flag being checked for Unicode availability returns 'not available' via RC 8. After the PTF is IPLed (required!), the field is all zeroes, which is OK. The fix moves the time stamp to UCCB+20 and zeroes out UCCB+10. In order to verify functionally, SYS1.SAMPLIB contains member CUNSISMA, which calls Unicode. RC 0 indicates Unicode is available, RC 8 indicates it is not available. If you run CUNSISMA today, you'll get RC 0. But if you use your favorite memory altering tool--we used Omegamon MZAP--to set UCCB+10 to D0000000 00000000, the program will get RC 8. After the fix is IPLed, UCCB+10 is all zeroes, and CUNSISMA gets RC 0. We could go further and IPL the system to December 16, but that's a lot of trouble just to see if IBM is telling the truth. ;-) . . .
