How's the software, you ask?

I made applications simpler, they need only request the cursors they want and insert their triples onto the instance stack.  Join will find and process the request.

All of that is working, I am now trying out simple applications, like text searching. The whole chain compiles and I run  simple joins from plain text sources.  Unit test is basically done, full system test and adjust is what I do now, and that is only a few days of work. All the basic attachments seem to work, and we have four.  All based on plain text.

I added a simple shell with two or three command utilities to interrogate the instance stack and see what is happening. Next I want to attack the complex multi-level joins through the memory attachment.
