Alias names are provided for many of the IBM-supplied print bands and trains. For example, if the data set were printed on a 3211, a request for the 1403 TN train would assign the T11 train. The assigned alias names that follow the naming conventions currently used in SYS1.IMAGELIB are:

The image and alias names are included in SYS1.IMAGELIB at system installation.

Some bands/trains, such as SN and G11, do not have aliases because neither has an equivalent band/train on the other printer. An installation can assign an alias, if it chooses. (For details about the ALIAS statement, see z/OS MVS Program Management: User's Guide and Reference.) If you do not specify a name (or alias), you must specify an installation-defined SYSOUT class or a printer routing code to assign the data set to the correct printer. If JES is directed to print a data set on a printer for which the specified image does not exist, JES notifies the operator. The operator can then cause the data set to be printed with a valid band/train or redirect the data set to the proper printer. If an installation defines a new band/train, it can supply an alias name for it through the ALIAS statement when including the image in SYS1.IMAGELIB.
