Some notes on my block editor

In my previous post I mentioned my block editor. This is a small editor that I've used for several years now.

My image contains 1024 blocks of 512 characters each. The blocks are formatted as 8 lines, with 64 character per line. The editor allows the user to enter text on each line, or at a particular place in the line. You can delete lines, or the entire block. It is possible to evaluate code contained in a block. Editing is done through a set of short words.

Though primitive, it's served me well through the years. I see it as a decent starting point for a better editor (in fact, in older Retro systems, this editor was extended to have a VI-style modal editing model and a syntax-highlighted viewer). I'll post more details on it in the near future.
