I have been looking for some time for a C Reference Manual from early 1973 (or late 1972) where Dennis comments that multiple array subscripts will eventually have Fortran-like syntax with commas separating rather than multiple sets of square brackets. That was the first C manual I had back when I first learned the language. Silly me, I discarded it when a newer one was issued, not realizing the historical significance of the earlier one. - Alan
