:I'm confused about the FontBBox entry that is supposed to be in every

:appears to be 4 numbers.  That is, if you do something like:
:
:/Helvetica findfont begin FontBBox end

:you'll have 
:	-166 -244 1000 966
:on the stack instead of the array
:	[ -166 -244 1000 966 ]

:So why does it push 4 numbers instead of the array?

It's an executable array (otherwise known as a procedure).  You can
get it to land on the stack by using

/Helvetica findfont begin /FontBBox load end

and you can use the "cvlit" operator if you want it to be a literal
array for some reason.
