That looks to me like a simple matter of a hard return where there
shouldn't be one. Would I be right in thinking '#BOXSIZE * 3.5 + 1;' should
all be in one comment at the end of the line?... or is that # part of some
advanced Perl syntax I'm not familiar with (I daresay I'm not much less of
a novice than Paul in the context of this list!).

In fact, now I look at the copy I saved, I see there are quite a few hard
returns where you wouldn't generally expect them - of course that doesn't
perturb Perl at all for the most part, as it's just seen as white space,
but when it happens in the middle of a comment it 'breaks' the comment,
thus uncommenting the part after the return.

And I'm quite certain these hard returns have come about merely through the
process of e-mailing.

 Cheers ... Chris
