Steve,
you confuse two different things - virtual memory and auxiliary memory.

In a virtual memory two contiguous pages will have adjacent addresses.
How it will be stored on a disk is entirely different matter - these pages
may be contiguous or not, they even may be on different drives.
It depends on many factors.

On iSeries you do not have to worry about such things - this is totally
transparent.

Larry,

so when a usrspc of say size 1 MB is created, 1MB of contiguous disk are
set
aside for it.
If the size of the usrspc is extended to 2MB does this mean that the entire
1MB have to be moved to the new 2MB sized location?
