Is there any way in hypertalk to get the types and id's of objects covering a specific location? For example, I'd like to write put objects at 200,300 into msg and have card field id 30, card button id 42 appear. I can loop through all the objects in the card, get their rect's, and check to see if the point of interest is within each rect. Is their a more efficient way that I've missed? -john John Rieman U. of Colorado Boulder, Colorado rieman@boulder.colorado.edu

It would be more complicated to keep track of newly created or moving objects, but still not all that difficult. So far I've been disappointed that more HC programmers haven't taken advantage of features of HC available though use of animation, message passing, dynamic attribute setting, object oriented features, and dynamic script modification. Your question reminded me of several ideas I haven't done much with yet, like buttons that move, communicate with other objects, interact with their local environment, and use functions and lookup tables to make decisions. Also, since a subset of Logo has been implemented in Hypertalk, let's have more interactive control of objects in stacks! Dan Dlugose UNC Edu. Computing Service
