Converting Old Programs

XPL0 programs from previous versions of XPL0 may require some modifications to before they will run. Here is some information about converting programs.

1. Standard Intrinsics. Most programs that confine themselves to standard intrinsics will usually run without any modification under EXPL.

2. Graphics, Mouse and Sound. Programs that use DOS calls and assembly language to perform things like manipulating bitmaps, playing sounds and accessing the mouse should make use of the extensive set of new intrinsics designed to replace these functions. These extended intrinsics provide a device-independent, flexible and high-speed ability to perform these tasks.
