I was using Fortran H on production code in about 1973 on Princeton's
360/91 and it worked fine.  It was a large (for the time) numerical
economic simulation that took forever to run.  Recompiling with H
rather than G and rewriting a couple of subroutines so they didn't
open and close a file every time they read a record from the disk made
a huge difference.
