Triple scripts use the concatenated t-block file format. It's one of the most portable application file formats in the world. Refer to the existing info about the triple script file format.
As the linked page indicates, you should NOT use the triple script file format for anything that is not actually a triple script. Programs are only triple scripts if they conform to all three of the triple script invariants. To experiment with similar concepts for files that are not valid triple scripts, it's not necessary to use the triple slash delimiter, so please do not abuse it for other purposes.
