Specifies the template for the name of the image copy data set. You can specify a data set name by using symbolic variables, or non-variable alphanumeric or national characters ($ # @). Each symbolic variable is replaced with its related value at run time to form a specific data set name. When used in a DSN expression, a substitution variable begins with an ampersand sign (&) and ends with a period (.).

The data set name generated must contain no more than 44 characters. For details, see Data set naming template.

Default value
None.
