How do I use zScript to open an application by its creator code?
Create a resource file and use ResEdit to modify the creator code to match the code for the application you want to open. Save these resource files in a folder whose pathname you can get from Director (like a subfolder below your current folder). Then use zScript and the ‘tell application “Finder” open alias…’ AppleScript command to open the appropriate resource file, which opens the application without you having to supply a pathname.
