This is a preliminary release for the benefit of those people who have expressed interest in the development of Zen.
The 1.0 release supports the complete semantics of the ELK Scheme interpreter, and a simple, but functional set of NextStep user-interface features. There are a few special things to be aware of.
1) The return key in the Listener doesn't quite do what you expect. In fact, in this version it really doesn't do anything useful. Use the Enter key to evaluate a Scheme expression in the Listener.
2) Hold down the shift key and use the left and right arrowkeys to skip over S-expressions in editor windows.
3) Certain ELK features, such as image dumping, are not tested yet. Use with care.
4) I am not yet ready to distribute sources. I will be eventually. Let me know if you want them.
I am interested in adding a number of features. Right now, some simple support for PostScript graphics under Scheme program control is at the top of my list. If there are features you particularly want to see, send me mail. I am inclined to concentrate on support for interface construction by direct manipulation as one of my top priorities.
