Creating and changing data set templates
Use the Create Data Set Template, Create
Like Data Set Template, or Data Set Template
Properties windows to build and manipulate
data set templates. Data set templates are
objects that define a data set naming convention,
DF/SMS parameters, and media parameters to
be applied to newly created data sets. Utilities
use data set templates to dynamically allocate
the data sets they require.
Using a data set template for naming data
sets helps you keep large numbers of data
sets organized by generating data set names
based on custom parameters defined in the
template. When using a utility you can specify
the name of a data set template instead of
creating the name for a new data set yourself
thus, making searching and identifying data
sets a simpler task.
