V (Volume)

A volume lookup is performed against the current tape database

D (Data)

The common tape record is built based on the information available at the time of the request

L (Label)

The current record contains a preformatted label image ready to print

S (Spinoff)

This request closes and reopens any dynamically allocated printers

C (Close)

This request is used to ask the Output processor to close all files
