This command links to the post-command section of the current PGC without playing back of the remaining cells after the cell issuing this command, and optionally highlight a specified menu button. A button value of 0 indicates no highlight. This command is useful to skip over a range of cells in a PGC.

Cells having cell commands are non-seamless by default. LinkTailPGC can be present only in cell or button commands. LinkTailPGC cannot be present in the First-Play domain. LinkTailPGC is commonly used in button commands to start the execution of commands in the post-command section section of the PGC having the cells issuing LinkTailPGC. This is the current PGC that is playing back the cell having the command LinkTailPGC.
