. ALGOL Y was intended to be a "radical reconstruction" of ALGOL. One such feature was the possibility to construct new proc mode's at run-time, which was criticized as the "ability to modify its own programs at run time" while, on the other hand, it would have brought ALGOL Y to the same level of expressiveness as

. "Initially the proposal for an update to Algol was Algol X, with Algol Y being the name reserved for the corresponding metalanguage. Van Wijngaarden produced a paper for the 1963 IFIP programming language committee, entitled “Generalized Algol,” which contained the basic concepts which were eventually incorporated into Algol 68
