Virtual memory map

The VAX virtual memory is divided into four sections. Each is one gigabyte (in the context of addressing, 2³⁰ bytes) in size:

Section	Address Range
P0	`0x00000000` - `0x3fffffff`
P1	`0x40000000` - `0x7fffffff`
S0	`0x80000000` - `0xbfffffff`
S1	`0xc0000000` - `0xffffffff`

For VMS, P0 was used for user process space, P1 for process stack, S0 for the operating system, and S1 was reserved.
