Toolbox-Based Routines for Macintosh Timing and Display

Pascal routines are described for performing and testing various timing and display operations on Macintosh computers. Millisecond timing of internal operations is described, as is a method to time inputs more accurately than tick timing. Techniques are also presented for placing arbitrary bit-image displays on the screen within one screen refresh. All routines are based on Toolbox procedures applicable to the entire range of Macintosh computers.
