Are there terminals out there with something like a "programmed string"
feature: escape sequences that can be programmed on-the-fly to expand
into strings of displayed characters?  Somewhat like the reverse
of programmed function keys.  The programming must be done by other escape
sequences, not from the keyboard.

I've been playing with data compression using a simple model like this,
going from a Unix machine to my own terminal emulator (on an Apple II).
I'm just wondering whether there are commercial terminals that can support it.

By the way, I get factor-of-two compression (4800 baud on a 2400 baud line)
on a good day, and almost always more than 1.5.
