MacLab is a program for which a demo was posted a little while ago. It has been slightly modified so that one may use it to do animation. MacLab allows one to display MacPaint pictures at a maximal rate of 30/second. The recent change has been to get rid of flicker that used to occur. (MAC PROGRAMMERS - BlockMove makes its memory move from end to beginning, so if you want to put fast sequential pictures on the screen you have to write your own memory move routine in assembler (using MOVEM if you want the fastest)). Each slide is pre-loaded, and it takes up 22K, of course, so the more memory you have, the larger the set of different slides you can switch between. Any requests for information or for MacLab should be sent here or to DC Software 1430 Massachusetts Ave., Suite 306-R Cambridge, MA 02138 -dan costin (duc@wjh12.harvard.edu)
