Line 25:
The algorithm reads eleven numbers from an input device, stores them in an array, and then processes them in reverse order, applying a user-defined function to each value and reporting either the value of the function or a message to the effect that the value has exceeded some threshold.

In the original paper, they gave the following example implementation "in a dialect of [[ALGOL 60]]", noting that ALGOL 60 was a later development than the languages actually discussed in the paper:<ref name="edpl"/>▼
=== Implementations in the original paper ===
▲In the original paper, which covered "roughly the first decade" of the development of high-level programming languages (from 1945 up to 1957), they gave the following example implementation "in a dialect of [[ALGOL 60]]", noting that ALGOL 60 was a later development than the languages actually discussed in the paper:<ref name="edpl"/>

Line 50 ⟶ 52:
* If the language does not allow programmers to define their own functions, then replace <code>f(a[i])</code> with an expression equivalent to <math>\sqrt{|a_i|} + 5x^3</math>.
▲== Implementations ==
▲In the paper, which covered "roughly the first decade" of the development of high-level programming languages (from 1945 up to 1957), the authors implement this algorithm in [[Konrad Zuse]]'s [[Plankalkül]], in [[Herman Goldstine|Goldstine]] and [[John von Neumann|von Neumann]]'s [[Flowchart|flow diagrams]], in [[Haskell Curry]]'s proposed notation, in [[Short Code (computer language)|Short Code]] of [[John Mauchly]] and others, in the Intermediate Program Language of [[Arthur Burks]], in the notation of [[Heinz Rutishauser]], in the language and compiler by [[Corrado Böhm]] in 1951–52, in [[Autocode#Glennie's Autocode|Autocode]] of [[Alick Glennie]], in the [[A-0 System|A-2]] system of [[Grace Hopper]], in the [[Laning and Zierler system]], in the earliest proposed [[Fortran]] (1954) of [[John Backus]], in the [[Autocode#Mark 1 Autocode|Autocode]] for [[Manchester Mark 1|Mark 1]] by [[Tony Brooker]], in ПП-2 of [[Andrey Ershov]], in BACAIC of Mandalay Grems and R. E. Porter, in Kompiler 2 of A. Kenton Elsworth and others, in ADES of E. K. Blum, the Internal Translator of [[Alan Perlis]], in [[Fortran]] of John Backus, in [[ARITH-MATIC]] and [[MATH-MATIC]] from [[Grace Hopper]]'s lab, in the system of [[Friedrich L. Bauer|Bauer]] and [[Klaus Samelson|Samelson]], and (in addenda in 2003 and 2009) PACT I and TRANSCODE. They then describe what kind of arithmetic was available, and provide a subjective rating of these languages on parameters of "implementation", "readability", "control structures", "data structures", "machine independence" and "impact", besides mentioning what each was the first to do.<ref name="edpl"/>
