    ALGOL 68-R was the first implementation of the Algorithmic Language ALGOL 68.
    In December 1968, the report on the Algorithmic Language ALGOL 68 was published. On 20–24 July 1970 a working conference was arranged by the International Federation for Information Processing (IFIP) to discuss the problems of implementing the language, a small team from the Royal Radar Establishment (RRE) attended to present their compiler, written by I. F. Currie, Susan …

    When was the ALGOL 68 language created?
    On December 20, 1968, the language was formally adopted by the group, and then approved for publication by the General Assembly of IFIP. ALGOL 68 was defined using a formalism, a two-level formal grammar, invented by Adriaan van Wijngaarden.

    Should not be executed in ALGOL 68?
    As defined in ALGOL 68, it did not work as expected, for example in the code: IF FALSE ANDF CO proc bool: CO ( print ("Should not be executed"); TRUE ) THEN ... against the programmers naïve expectations the print would be executed as it is only the value of the elaborated enclosed-clause after ANDF that was procedured.

    What is formatted transput in ALGOL 68?
    "Formatted transput" in ALGOL 68's transput has its own syntax and patterns (functions), with FORMAT s embedded between two $ characters. ALGOL 68 supports programming of parallel processing.
