I am just looking at how to generalise the function, so it could be
used as a recipe for any pagelist to be broken into parts.
But I am finding one big problem:

The BreakPageList function needs an accurate count of the pages
the pagelist displays. How can I get that in  a general solution?
(:pagelist .... fmt=count :) is no help here as it only displays the
count, but this can't be used in a function.

For the forum I use

$FoxPageCount = count(ListPages("/^$page-\\d*$/"));

which counts specific pages in the group, specified by a name pattern.
This is no use in a general solution, where we don't know what kind of
pages pagelist lists.

Is there a method to get an accurate pagelist count for use in a
function called by markup which will determine the pagelist output by
specifying the variables used in  (:pagelist .....  count=$From..$To:)
?
