With my recent introduction to writing Mac programs in C, I can tell you that writing a program for the Mac is no simple task, many things have to be taken into consideration, and from what I have seen in the other software available, everyone but Bill Atkinson himself has done it wrong. Many inconsistencies are due to the fact that the Inside Mac document is quite a bit behind the current standard, with certain standards different (e.g., the feature-mumble commands for the edit menu). These Pascal programs are inherently slower and larger than assembly language counterparts, and therefore slow down the Mac. Finally, here is a request: When you use MacPaint, each change increases the size of the file, it would be nice if there was some way to condense the information (put it on the screen and then force a screen dump, or something to that effect) _emt
