To answer the original question, standard Fortran 90 allows dynamic
allocation through two mechanisms (one of which is the very well thought
out ALLOCATABLE attribute, and the other is a very poorly thought out
pointer facility).  The Fortran 77 standard does not allow dynamic
allocation.  The LWG Fortran specification included a pointer facility
(which was both simpler and better than the Fortran 90 version) which
has been adopted by many vendors as an extension to Fortran 77 - most
notably (from my point of view) both Cray and Sun use the LWG pointer
mechanism.

Note: the LWG Fortran specification was written by the DOE Language
Working Group (LWG) in final form in 1982.  I has many features in
it which are more desirable than the Fortran 90 counterparts.

FORTRAN 77 is the designation recommended by the standard document itself
(ANSI X3.9-1978, Forward):

   It is suggested that the designation FORTRAN 77 be used to distinguish
   this standard from previous FORTRAN standards and any possible future
   revisions.

Similarly, "Fortran 90" is actually the *title* of the ISO version
of the new standard.  Whether these designations are *official*
or merely *officially informal*, they are clearly the appropriate
names to use.  As far as I can tell, the Fortran 90 document uses
these terms throughout.  (It solves the question of whether Fortran 77
is upper- or lower-case by using small caps for all letters after the
initial `F'.)
