Yep. As Paul B pointed out, 'open for access' has nothing to do with
the Finder. These commands are part of the Standard Additions osax.
Yes, I know it's a standard addition. I was illustrating what not to
do. As for how bulletproof these commands are, I disagree. Run this
twice:
tell application "Finder"
set rn to open for access "Gort:Users:sjmills:Desktop:testblah" with
write permission
write "bob" to rn
close access rn
end tell
One the 2nd run, I get "Finder got an error: Duplicate file name. some
object". Take out the Finder targeting and I get "Duplicate file name.
Gort:Users:sjmills:Desktop:testblah".
Now add the class "file" before the pathname and it works. Clearly,
it's a bug that it doesn't work a 2nd time if you pass a pathname
string. THIS is the problem I always have, and it's not obvious that I
have to remember to type "file" in front of it, because almost every
other app or command I regularly use that takes a file reference works
no matter what when I pass a pathname string instead of a file or
alias. If other apps and commands are written to be smart enough to
always accept a string, then these commands should be too.
The dictionary is clear...
write: Write data to a file that was opened for access with write
permission (defined in: StandardAdditions.osax)
write anything -- the data to write to the file
[for double integer] -- the number of bytes to write; if not
specified, write all the data provided
[starting at double integer] -- start writing at this position in
the file
to anything -- the reference number or alias or file reference of
the file to write to
[as type class] -- how to write the data: as text, data, list, etc.
'write' doesn't accept paths at all. But silent coercion makes you
think that it will. I assume that's done to avoid having to tell the
Finder to make a new file and then use Std Additions to read/write it.
Damn user friendly AppleScript strikes again!

Even the Std. Additions ones?
