From: Gustavo Fernandez <FERNANDEZ@SU-SCORE.ARPA> Some answers to questions previously placed on the board... The documentation to the vertical retrace manager explicitly states that you cannot issue any toolbox calls that allocate memory from an interupt handler. Since most toolbox calls can under the right circumstances, trigger a memory request, it is best to not call the rom at all! Blockmove works under all circumstances. Cary Klarke:"BlockMove is Very, Very, fast, and will optimize its move strategy depending on the size of the move." Use it. You are right, it is best not to play with A5 at all. Almost everything in the Mac depends on it. The document, "The Structure of a Macintosh Application" under the "application" tab of inside mac tells all about how to interface with the finder. -------
