Is it possible to control a DOS app, i.e., sending it keystrokes, i.e.,
simulate user typing keys with Euphoria. . .?
And, is it possible for a Euphoria program to actually do a text search of a
text screen already running?
TSR Land?

Yeas, TSR, using BIOS calls (msdos isn't reintrant), or use DRDOS. You
can stuff the keys into the keybd buffer, and then tell the other program you
did so with the buffer_count byte.

Yes, look in the screen buffer,, C000-?. The buffer location, size, format, etc
can be changed tho. I haven't thought of this stuff in ages.

I think you can extract the contents of a standard 80x25 vga display with
peek({#B800, 4000}) -- 80x25 = 2000 characters, but each character
also comes with an extra byte which stores the color attributes.
To extract just the text, use a loop by 2.
You could probably do the same thing with save_text_image()
