Just to add to the above; RATFOR (https://en.wikipedia.org/wiki/Ratfor https://en.wikipedia.org/wiki/Ratfor) was implemented as a preprocessor to Fortran with its control structures almost identical to those of C. So going from the freedom of C syntax to the straitjacket of Pascal might have been too much and hence the Pascal paper. Here is the pdf of Brian Kernighan's paper on RATFOR - http://www.econ.uiuc.edu/~roger/research/repro/ratfor.pdf http://www.econ.uiuc.edu/~roger/research/repro/ratfor.pdf
