I know - and I had intended to refer explicitly to IV which? would also have inferred II
etc. I never used 66 so could not comment at that level.? I did use 77 though and know
that it was changed.? I was comparing earlier Cobol (68) with earlier Fortran iter
construct. ??

Don't forget that the DO loop in Fortan has not

It differs. What you describe is how it is in FORTRAN IV and older.
It was changed in FORTRAN 77, so that a DO loop can run zero number of times as well.
