However, Modula-2 is also a *systems* programming language! If I am programming a device that is block mapped, it might be efficient to handle my memory 32 bits (integer)) at a time. However, if I need to do other operations on that memory, it might be more efficient to use 8 bits at a time. You can see that a simple pointer conversion will allow me to do both. ------------------////////////////////\\\\\\\\\\\\\\\\\\\\------------------ | Patrick Draper Disclaimer: I can't control my fingers, | | draper@umcc.ais.org I can't control my toes! - Ramones | | University of Michigan | | Computer Club We are a nation of laws, not people | ------------------\\\\\\\\\\\\\\\\\\\\////////////////////------------------
