> The first implementation of the standard, based on the late-1968 draft Report, was introduced by the Royal Radar Establishment in the UK as ALGOL 68-R in July 1970. This was, however, a subset of the full language, and Barry Mailloux, the final editor of the Report, joked that "It is a question of morality. We have a Bible and you are sinning!"[31] This version nevertheless became very popular on the ICL machines, and became a widely-used language in military coding, especially in the UK
Burroughs Algol was based on Algol 60, Pascal was derived from Algol W which forked off from Algol 60 well before Algol 68, PL/I also predates Algol 68.
