Hi Folks,

If you are a user of the LOOK TSO command to browse active storage,
from CBT Tape File 264 (www.cbttape.org - see Updates page), you have to
be informed of the following development:

Important note, for the LOOK command to work:
--------- ---- --- --- ---- ------- -- ----
Note from Sam Golob: The LOOK program needs
a PARMLIB setting in the active DIAGxx member:
****
>>>>>>>> VSM ALLOWUSERKEYCSA(YES) <<<<<<<<

This was the default until z/OS 1.8, but in
z/OS 1.9, VSM ALLOWUSERKEYCSA(NO) is the
default. It now has to be specifically set to
VSM ALLOWUSERKEYCSA(YES), or LOOK will abend
with a SB0A, reason code 5C.
-------------------------------------------------

This is one of the "gotchas" that get you when you go to a new z/OS
release. Better to be informed, than not informed. The solution was
discovered, when I looked up the SB0A, reason code 5C abend in the z/OS
1.9 System Codes book. Since a lot of people use the LOOK command (or
at least they SHOULD), I figured I'd spread the word around.

All the best of everything to y'all........

Sam
