Can anyone explain the difference between P0 and P1 space on a VAX?
Text and initialized data segments (on BSD 4.3, at least) wind up
in P0 space; unitialized data (i.e. stack) is placed in P1 space.
The two regions are accessed using different base registers; P1 is
a bit tricky to work with in comparison to P0.
Explanations to this ignorant layman are appreciated...
