The FORM specifier indicates whether the file is being connected for binary (WNT, W9*), formatted, or unformatted data transfer. It takes the following form:
|'FORMATTED'||Indicates formatted data transfer|
|'UNFORMATTED'||Indicates unformatted data transfer|
|'BINARY'||Indicates binary data transfer|
The default is 'FORMATTED' for sequential access files, and 'UNFORMATTED' for direct access files.
