Format Identifier

f is a format identifier and can be:

See "Runtime Formats " for details on formats evaluated at runtime.

If the optional characters, FMT=, are omitted from the format specifier, then f must appear as the second argument for a formatted write; otherwise, it must not appear at all.

f must not be an asterisk for direct access.

f can be an asterisk for internal files. @

If a file is connected for formatted I/O, unformatted data transfer is prohibited, and vice versa.
