Ok, "REAL A(1)" is the old-old way, "REAL A(*)" is the old way,
"REAL A(N)" is the new way, "REAL, DIMENSION(N) :: A" is the
new-new way. :)
By this I mean that assumed-size arrays are often trivially
replacable by the semantically superior adjustable arrays
("REAL A(N)"), though of course before either existed,
people often used "REAL A(1)". Though there are still
(in F77 anyway) valid uses of assumed-sized arrays that
are not easily replaced by adjustable arrays.
