When we replaced our VT52's we found out you could send out series of cursor
control codes on VT100's to move the cursor and then output a character.
Early star trek games on video terminals used this instead of sending out
spaces and characters. You could also plot line graphs and barcharts using
control codes.
In fact, many things (like xterm) still support that. I use it to move the
cursor to the upper-right corner of my screen, print the time, move back to
the lower-left and display a prompt as part of my bash setup :) it works
right in xterm and on most vt100-emulating terminals I've used...
