Is Binfile broken?

[Bob Sneidar]

Thanks Richard. I get “Can’t open that file.” in the result for the write. Very informative. ;-)

Now I have to figure out *why* it can’t open that file. I fear it might be Mavericks sandboxing that is getting in the way. It is a folder on my desktop, and while I changed the Everyone permissions to write, it still seems to be giving me fits.

You're not using the URL syntax, but both the URL method and open/write/close should work, with both text and binary modes.

To diagnose problems with file access (and many other circumstances where error-checking is useful), check the result after attempting the action.  With file access it can be very help to include a call to sysError there, so you can see what the OS is complaining about, .e.g:

   open file theDestFile for binary write
   if the result is not empty then
       answer the result &"("& sysError() &")"
   end if
