But this only allows you to adjust them within the bounds of what has been
defined elsewhere, so only limited adjustability.

It allows pointer arrays inside data structures, the actual size of which
may be specified within the calling or called routine (but pointer arrays
are mildly more difficult to declare and initialise).

Fortran2002 will allow allocatable arrays within data structures, according
to the best authorities.  Since Fortran2002 will also drag the language
kicking and screaming into the object-oriented era, I'm sure you will
welcome it. :-)
