It's been many years, but I seem to remember porting the NCAR Graphics Package written in FORTRAN IV to FORTRAN 77 on a Data General MV series box.
If memory serves, they had a trick to create simulated pointers, by declaring a one element array somewhere in memory, and then indexing way outside of its bounds in order to point into other areas of memory.
I don't remember the details, but I seem to remember there was a statement ("EQUIVALENCE"?) that facilitated this magic.
