- A resident program that allows you to draw boxes and lines using most any
- text editor.
-
- To use it, mark the corners of the box or the ends of the line with happy
- faces. Use Alt-1 () for single lines and Alt-2 () for double lines.
- When you're ready, hit Alt-_ (underline) to draw the box/line. That's all
- there is to it.
-
- BOX works by generating keycodes to draw the box/line (getting the
- intersections right) and stuffs them into a typeahead buffer. Your
- editor should read them (via int16) and perform just as if you had typed
- them in.
-
- The only possible problems I can think of are:
- ..Both happy faces must be on the screen when you hit Alt-_. I read the
- screen directly (B000/B800) so you gotta have an IBM compatible display
- adaptor.
- ..Don't get right up against the right-most column or the bottom-most line.
- I have no way of knowing what your text editor does after you type something
- in column 80 (new line, scroll left, etc.).
- ..Make sure you are not in insert mode.
- ..Your editor must be reading the keyboard via DOS or BIOS calls. If he
- intercepts int09, get another editor. There are good reasons to
- address the screen directly (performance), but absolutely no reason
- to read the keyboard directly.
