layer_name:s Name of the layer

show:s The processing instruction can take a fourth parameter which would be a showstring that should be applied if the layer cannot be applied to the current page.
When using <?layer> to control under/overlay modes it is important to note that:

They do not get applied to the following pages during autocopy.

Ordinary layers cannot be controlled by this PI.

When creating a layer, a parameter value of ? is required by the mode parameter of tplay. In other words, the Mode: entry field in the Add/Remove Over/Underlay dialogue box must be set to 'Controlled by <?layer>'. For more information see tplay.
