PS: Watch it if you clip this from Apple Mail, sometimes spurious characters not good for shell scripts creep in depending on encoding factors. You should be able to get rid of them by using the 'nano' editor.

Thanks! I note this commment from the end of the documenation you mention:

"The AppleScript command is a stopgap command to fill the place of exec on the Mac. It is not a supported command, and will likely change as we broaden it to allow communication with other OSA languages."

That's from System 7 as well (Tcl did not have the 'exec' command implemented on OS 7/8/9). It's position on OS X is at the highest per- platform level of extensions. The directory containing those is located at /System/Library/Tcl.

As things stand today, using TclApplescript will be faster than using osascript because it keeps the component loaded until the caller quits or you call 'package forget Tclapplescript'.

BTW, the original author of this extension is Jim Ingham. He has been an engineer with Apple since OS X (on the debugging team) but championed Tcl on the Mac for 10 years before that at Sun and Lucent.
