	Haven't looked much at Fortran-90/95 then... 

	Variable declaration gained a POINTER qualifier, and there is an
ALLOCATE intrinsic to obtain memory.

	And with difficulty one could get the result in DEC/VMS FORTRAN-77
since DEC implemented (across all their language compilers) intrinsics
controlling how arguments are passed -- overriding the language native
passing: 
		CALL XYZ(%val(M))
would actually pass the value of M, not Fortran default address-of, with
the result that XYZ would use that value /as/ the address of the actual
argument. (Others were %ref() and %descr() -- descriptor being a small
structure with the address reference along with, say, upper/lower bounds;
often used for strings).
