This article has some problems. The claim that APL (in this sense) predates FORTRAN is critically dependent on whether you are talking about proposals, manuals or working versions.
The Fortran manual dates from 1958, but the proposal dates from 1952, a year before APL.

If you're talking published proposals then Plankalkul dates from 1948 even though it wasn't implemented until 1998. If you're talking working implementations, the A-0 compiler was operational by 1952 and its successor, the A-2 compiler, was being sold to the general public in 1953. -- Derek Ross | Talk08:16, 14 July 2013 (UTC)[reply]
