WikiSh has this capability using a syntax like {$:var${counter}} to work
with "pseudo-arrays".  If you think you would be interested in this I can
code it up for you and put it out on the WikiShExamples page.

It would look *something* like this:

Set i = 1
Set --pv total = 0
While test ${i} -le 35
   set --pv total += {$:var${counter}}

That would be placed in a page somewhere (Mygroup.Totalcode, for instance)
and then run from your page via {earlymx(wikish source Mygroup.Totalcode)}.
Then you could access the variable as {$total} elsewhere within your page.  

No guarantees on this - I haven't actually run it and so I might have typos
causing syntax problems or something.  

This is a case where WikiSh works just fine entirely in "read-only" mode
which is the default.
