On input from a file connected for sequential access, the rest of the current record is skipped andthe file positioned at the start of the next record.On output a new record is created which becomes the last and current record. For an internal fileconnected for direct access, the record is filled with blank characters. For a direct access file, therecord number is increased by one and the file is positioned at the start of the record.Multiple slashes are permitted, thus multiple records are skipped.5.5.2.21 The : Format Specifier – Format TerminationThe (:) control terminates format control if there are no more items in the input/output list. It hasno effect if there are any items left in the list.5.5.2.22 $ Format ControlThe $ field descriptor allows the programmer to control carriage control conventions on output. Itis ignored on input. For example, on terminal output, it can be used for prompting.The form of the $ field descriptor is:$5.5.3 Variable Format Expressions ,Variable format expressions are supported. They provide a means for substituting run-timeexpressions for the field width, other parameters for the field and edit descriptors in a FORMATstatement (except for the H field descriptor and repeat counts).Variable format expressions are enclosed in "" and are evaluated each time they areencountered in the scan of a format. If the value of a variable used in the expression changesduring the execution of the I/O statement, the new value is used the next time the format itemcontaining the expression is processed.5.6 Non-advancing Input and OutputNon-advancing input/output is character-oriented and applies to sequential access formattedexternal files. The file position is after the last character read or written and not automaticallyadvanced to the next record.For non-advancing input/output, use the ADVANCE='NO' specifier. Two other specifiers apply tonon-advancing IO: EOR applies when end of record is detected and SIZE returns the number ofcharacters read.Fortran Intrinsics 167
