What else would it possibly mean?

k is very common shorthand for kB, at least historically.

14000 lines of assembler?

Something along that line (oops, pun not intended). I was thinking 14000 of something, not sure exactly what that is, until I realized it was kind of obvious.

Indeed a decade ago I would not have any doubts. Using "k" to refer to "kB" was much more common.
