Report on the algorithmic language ALGOL 60

On the Origin of Recursive Procedures

“…What it does use is the call by name mechanism, whose semantics are specified as follows: 'any formal parameter [called by name] is replaced, throughout the procedure body, by the corresponding actual parameter' [24,Section 4.7.3.2]. Given that the procedure identifier gips appears in the fourth parameter passed by name to the procedure gips, and given that this parameter is evaluated for each possible value of n passed to fibonacci, it is clear that 13 It is inspired by the 'general problem solver' in [27, p. the procedure gips is activated recursively: for any n ≥ 0, the procedure gips is activated two times at the same moment, at least once.…”

“…High-level is a matter of perspective, though. Algol was introduced as a language for the specification of algorithms [8] and was high-level with respect to assembly language. Now we consider the Algol-like languages such as C and Java as low-level implementation languages.…”

From qd to LR, or, how were the qd and LR algorithms discovered?

“…Firstly, starting around 1955, his main preoccupation for more than a decade was the development of the Algol60 programming language (see Backus et al, 1960Backus et al, , 1963, the description of its usage for basic problems of numerical analysis (see Rutishauser, 1967) and the creation of open-source high-quality programming libraries (see Rutishauser, 1961;Wilkinson & Reinsch, 1971). At the same time, he published a large number of papers on various topics in numerical analysis.…”
