You are definitely right on that. I forget what it was intended to run
on, probably some minicomputer like a DEC System-10 or -20.  Hmmm...  I
wonder if it would compile with Fortran-80 on my TRS-80.  That might be
fun to see.  I even have corrected sources around here somewhere because
after all those years of people using it I found a few bugs in the two
sets of sources that were floating around the Internet.  :-)
