I have a program wich will work for V2.x, but is broken in V3.0. You
basically just replace the contents of CTL$T_USERNAME (which is write
protected, so you have to modify the protection on the page first...)
It is really straight forward, except for the use of SYS$CMKRNL to get
into kernel mode so we can do a SYS$SETPRT on the page to make it writable,
write on it, and reset the protection. In V3.0, the data is also stored
in the JIB, so you would have to find out that location name and change
it too. If you want sources, I have a MACRO program and a C program
I can make available.
