Subparameter definition

BINARY: The file described by the DD statement is a byte-stream file and does not contain record delimiters. The access method does not insert or delete record delimiters, <newline> character X'15'.
TEXT: When you copy MVS data sets to text files in the z/OS UNIX file system, a <newline> character X'15' is appended to the end of each record.
RECORD: Indicates that the data consists of records with prefixes. The record prefix contains the length of the record that follows. On output, the access method inserts a record prefix at the beginning of each record. On input, the access method uses the record prefix to determine the length of each record. The access method does not return the prefix as part of the record. Code FILEDATA=RECORD when you cannot code FILEDATA=TEXT because your data might contain bytes that are considered delimiters.
Note:
The record prefix for FILEDATA=RECORD is mapped by the IGGRPFX macro. This is different from the record descriptor word (RDW) that is in z/OS physical sequential format-V data sets.
