Checking return values from the File routines.
Q. How can I tell when an error occurs in FileRead()? The docs mention that errors will be set "in the thread's error value." What is that and how do I access it? A. FileRead will return -1 and you can then use ThreadGetError(). It returns a word with the thread's error value. It should be one of the enum type FileError (file.def) or Error (in file.h).
