Introduction to MPE XL for MPE V Programmers Migration Guide

Chapter 10  Converting Data Types 

This chapter describes the differences between MPE V/E and MPE XL data
storage techniques and the implications for the programmer.  The MPE V/E
format of floating-point real numbers and the word size is not changed in
MPE XL Compatibility Mode (CM), but is different in MPE XL Native Mode
(NM) and some files will need to be converted; a sample program for
conversion is included.
