I don't work with records too often and I've run into
a couple of puzzling situations:
1.
A project I started earlier this year (in OS X 10.3) used records constructed
with vertical bar characters, for example: {|a|:somevalue, ...}.
AppleScript will no longer create new labels like this, but the old labels
still work. Why?
2. Suppose r is a record only one of whose labels is known.
For example, r = {a:somevalue, ... }.
I need to create a new record that contains everything in r
except property a. (I really, really need this!)
One would think this would be as easy as something like ...
set n to r
delete a of n
which, of course, doesn't work. Any ideas?
Looks like a job for good ol' Satimage.osax' "suppress item" command:
set r to {a:"somevalue", foo:"bar"}
suppress item "a" from r
--> {foo:"bar"}
Caveat: "suppress item" does not suppress the item from the original
record! "suppress item" returns the changed record but leaves the
original record unchanged.
