Introduction to MPE XL for MPE V Programmers Migration Guide

Segmenter 
(changed) 

MPE XL retains the MPE V/E segmenter program in CM for backward
compatibility.  The commands and intrinsics will be familiar to the MPE
V/E programmer.

Because of virtual memory, segmenting is no longer necessary.  MPE XL
emulates segmentation in CM. MPE XL does not support segmentation at all
in NM.
