This attribute is used only when executing a script from a command line on Windows. When the application is launched from the command line, the –r or –s command line flag causes the application to run a script (from a file or from a string, respectively).

If this attribute is set to true, After Effects will exit after the script is run; if it is false, the application will remain open.

This attribute only has an effect when After Effects is run from the Windows command line. It has no effect in Mac OS.


Boolean; read/write.
