- Visual Editor
-
- This editor, unlike the Block Editor (B100), is grid-based
- instead of being command-based. It requires the AT-XY, COLS
- and LINES words to be implemented.
-
- It is loaded with "125 LOAD" and invoked with "VE".
-
- This editor uses 17 lines. The top line is the status line and
- the 16 others are contents lines. The content shown is that
- of the currently selected block.
-
- All keystrokes are directly interpreted by VE and have the
- effect described below.
