Ok, that makes sense.  But how do you get it to take a group name?
something like

function hgsubgroup($x=$Group) {

Pardon the sloppy notation, just trying to get the idea..

It's also a bit tricky.  As it is, Hg generates the appropriate number
of pagevars dynamically based on the number of hyphens in the group
name.  In a pagelist, theoretically, that number would be variable
depending on the individual pages.  Would that mean each variable
would have to have a separate line calling the function, something
like

FmtPv [$g1] = ' hgsubgroup($x={$group}, level=1)  ';
FmtPv [$g2] = ' hgsubgroup($x={$group}, level=2)  ';

This would mean, it would only work to a predefined number of
levels--say 5 or 10, rather than unlimited.  Am I correct?

Of course, if it could automatically make these variables available to
a pagelist as it iterates through its pages, it would be worth it. I
would try and tackle it, but not sure I fully get it.
