Except when I need to pass the array to the procedures which do the work.

I could rewrite the procedures to accept pointers ... then the package spec, and
the older apps which used the package. But the renamed array worked for all
these.

(Arguably it's not portable, because another Ada compiler might try passing the
whole array by copy... or is that outlawed by the LRM?)
