Paul, the only storage key that has the special attribute "can be written from any PSWkey" is key 9 (since the bit in on all the time)
the other way round is "with PSWkey 0 you can write any key storage". This is way more powerfull (and dangerous) than an application in key "any<>0" writing to key 9. -- Martin Pi_cap_CPU - all you ever need around MWLC/SCRT/CMT in z/VSE more at http://www.picapcpu.de
