You mean Winkler's? I'm not sure myself. I do note though that global
properties in HyperTalk can be expressed as properties of HyperCard -
for example, "if the suspended of HyperCard is true..." Written this
way, there's no ambiguity - all properties are "of" something - and
it could be that leaving off the "of HyperCard" was originally a
Differentiating between global properties and no-parameter functions
is difficult for me too, for what it's worth. (It's the main reason
that for "HT 2.2: The Book", I reorganized the language reference to
put the terms in alphabetical order, instead of grouped by type of
term - with the first edition, I was always having to look under both
Functions and Properties to find things.)
But I rarely use the () form for functions that don't take a
parameter, so in practice the confusion isn't normally a problem for
me personally when scripting. Just when looking things up. ;-)

I think so. (But it's strongly recommended to always use "the" to
reference properties; not using "the" is one of those things that
might not always be supported, so....)
