incomprehensibly slow. I guess it would load the memory to an

The last time I dug around a bit for model 20 software, I was surprised
to find that there was not only a FORTRAN, but a PL/I and a COBOL
written for the thing.
By and large, the only applications that I ever saw were RPG. I can't
begin to imagine how slow a COBOL would be, much less a PL/I.
