THINK Projects When debugging a small program that uses FaceIt, 16K for the stack size and 512K for the zone size work well. There is no need to provide the project with the name of a resource file since this is done explicitly in your code (via uName). One idiosyncracy to be aware of is that you will not be able to break into, or set breakpoints in, code that belongs to FaceIt or other FaceWare modules. If you can't get the THINK project files to open it's probably because you have an earlier version of the compiler. Simply create a new project file and determine which files you need from the "include" statements or "external" references in the demo programs. If you cannot compile a file due to undefined toolbox-related types, either include the files that define such types, or change the types to simple handle, pointer, or integer types of the same size.
