Hmm, see below.

I have to (reluctantly) agree. Euphoria has 31-bit integers.
Try and ignore that and you risk opening up a world of pain.

Rob, that *is* a knee-jerk reaction. Al's solution is perfectly fine
in terms of pretty_print. I can't see a problem with it anyway ( bar
foot-in-the-door for 32-bit integer support ).

Absolutely agree, 100%.

Ditto, this is trivial.
However, I do want to stress: Anyone bar Rob making changes to
Euphoria\include\misc.e\pretty_print() itself I would *STRONGLY*
discourage. There is nothing like making such a change to your own
machine and then weeks, months, or years later wondering why the same
program fails miserably on an apparently identical machine.
Editing a *copy* of that file is, of course, fine.
Even if 2.5 is looming too close, I see nothing even slightly worrying
with the following (though I doubt it will ever help anyone much):
if integer(a) then
-- By Al Getz 26/5/2004: to print 32-bit ints, make a copy of this
-- file, and replace the above line with:
-- if a-floor(a)=0 and -#FFFFFFFF<=a and a<=#FFFFFFFF then
Regards,
Pete
