Can someone out there give me a quick answer to the following?
A few years back, I had to write a routine that would allow an image
running with CMKRNL privilege to chage it's UIC/USERNAME by poking at the
PCB. My macro was/is very rough, but i seem to remember seeing something
in a piece of DEC code (it MAY have been DECUS code) that basically said
'play around in this area at your own risk - DEC may choose to maim the
current layout at any time...'
My questions are:
1) Is it indeed such a bad idea to diddle these protected areas
2) Where can I get the original DECUS (i believe) code that did this?


Thnx for any help you can provide.
