Overview of Differences: MPE V/E and MPE XL There are major differences in developing programs in MPE V/E and in MPE XL. These differences may not be apparent at first glance; the model is the same, but components are different. One difference is that you have two programming modes, NM and CM. During operation, a program can switch between the modes. MPE XL CM emulates MPE V/E for backward compatibility. It maintains the appearance of segmenting, but the virtual memory of MPE XL has made segmenting unnecessary. New MPE XL features that are not available on MPE V/E include: * Dual programming modes * Native Mode program development * Mixed mode programs
