What is the meaning of the term "format", as used in the following comment I received to a question I posted on this forum:
LaTeX3' isn't released as a format: perhaps you mean expl3?
The answer I received to the above mentioned question also mentions this term:
You can dump a format from the current expl3 but it will just do nothing because it doesn't provide basic things like an output routine. If you are already running some format (Plain TeX, LaTeX2e, ConTeXt, lollipop, etc) you can input the expl3 macro package and use everything it provides.
I think you are asking whether there exists a format which has expl3 preloaded, to which the answer is no.
