The INFDS keyword lets you define and name a data structure to contain the feedback information associated with the file. The data structure name is specified as the parameter for INFDS. If INFDS is specified for more than one file, each associated data structure must have a unique name.
An INFDS must be coded in the same scope as the file; for a global file, it must be coded in the main source section, and for a local file, it must be coded in the same subprocedure as the file. Furthermore, it must have the same storage type, static or automatic, as the file.
