Template types and structure
A File Manager template is a collection of information that you can use to select and format records and fields in an application data set.
The template provides File Manager with a logical view of the data to be used when editing, viewing, copying, printing, and creating data sets. Templates can be based upon the definitions in COBOL copybooks, PL/I INCLUDE members, and HLASM copy members. Additionally, record structure descriptions can be extracted from complete COBOL, PL/I, or HLASM source programs. Alternatively, you can create your own record structure description in a dynamic template.
