An early version of Pascal-ish syntax diagrams was used by Huskey, Love,
and Wirth in . These "syntax charts" were introduced by Taylor,
Turner, and Waychoff in 1961 . Syntax charts were a direct
transliteration of (recursive) BNF descriptions; I don't think that they
employed the iterative "loops" that you find in the Pascal diagrams.
However, at about the same time, Glennie devised a version of syntax
charts which could be used to build a top-down parser from BNF definitions
. Glennie's tech report is probably impossible to find (and I think
that's the reason Glennie fails to receive much credit), but you can see a
use of "Glennie Recognizers" in a paper by Kanner, Kosinski, and Robinson
Other representations that you'll want to examine are: Conway's "separable
transition diagrams" ; Vere's "translation equations" , and; Cohen
and Gotlieb's "syntax graphs" . Cohen and Gotlieb begin with recursive
syntax charts, and perform a number of transformations, yielding
Pascal-ish syntax diagrams with iterative looping.
