Simple and multiple format logical files in DDS

You must specify the PFILE keyword at the record level for simple and multiple format logical files. In a multiple format logical file, a record format can use only the fields common to all the physical files specified on the PFILE keyword for that record format.

Specify the entries in the following order to define a simple or multiple format logical file:

Optional: File-level entries
Record-level entries
Optional: Field-level entries
Optional: Key field-level entries
Optional: Select and omit-field level entries

Repeat steps 2 through 5 for each record format in the file.

The following example shows a multiple format logical file coding example.
