## Open File by the OS

This function is used to open a file by the OS's default application for the files of that type. For example, files with a .txt extension will typically be opened by TextEdit.

The path may contain any of the escape sequences described in Escape Sequences. At runtime, the path to a database must be absolute (/) or relative to the home folder (~/).

The action test state will be set to true if the open succeeded, otherwise false.

The statement is not valid while batch processing.
