	Classical FORTRAN for everything (though VMS added overrides to permit
descriptors and accessing either the passed address AS the value or passing
a value AS the address).

	Ada depending upon the type of object and the in/out qualifiers (I
think it even permits value/return semantics rather than reference
semantics for IN OUT parameters -- arrays, strings, and records tend to use
by-ref, base numerics using by-val if IN, and by-ref for OUT.
