Similar, and maybe more related to the article's topic: Commodore BASIC also saved the commands as tokens, so you could enter abbreviated commands like

  10 ? "Hello"
  20 gO 10

and a LIST command would yield

  10 print "Hello"
  20 goto 10

So saving commands as tokens in memory and formatting them on output was somewhat common back then.

The speccy was more advanced in terms of this (as mentioned in the parent comment), and it had the better BASIC for sure.
