I know this is apple-script...but may I ask a really simple question.
The AS Implementors list is probably more appropriate for this sort
of stuff, but anyway...
What do the terms "want, form, seld" of the object specifiers
actually stand for; or another way of asking is how does "seld" end
up meaning the actual specifier, want the class of object and form,
well that's a little easier to guess...I think ?
'want' = four-char-code indicating desired element(s)'s class code
(e.g. 'docu' = document), or 'prop' if it's a property specifier
'from' = an object specifer identifying container object(s)
'form' = four-char-code indicating how the element(s) should be
selected (by index ['indx'], name ['name'], etc.), or 'prop' if it's
a property specifier
'seld' = selector data (e.g. in a by-name specifier, this would be a
string)
Inside Macintosh: Interapplication Communication has all the gory
details:
It's pretty ancient and some parts no longer apply in OS X - e.g. the
comms toolbox chapter - but if you've a burning need to know the
lower-level details (or are just seeking relief from chronic
insomnia) it's still the one to read.
BTW, can I ask what's your interest in this stuff?
