Rules for Formatted Sequential READ Statements

Formatted, sequential READ statements translate data from character to binary form by using format specifications for editing (if any). The translated data is assigned to the entities in the I/O list in the order in which the entities appear, from left to right.

Values can be transferred to objects of intrinsic or derived types. For derived types, values of intrinsic types are transferred to the components of intrinsic types that ultimately make up these structured objects.

For data transfer, the file must be positioned so that the record read is a formatted record or an end-of-file record.

If the number of I/O list items is less than the number of fields in an input record, the statement ignores the excess fields.

If the number of I/O list items is greater than the number of fields in an input record, the input record is padded with blanks. However, if PAD='NO' was specified for file connection, the input list and file specification must not require more characters from the record than it contains. If more characters are required and nonadvancing input is in effect, an end-of-record condition occurs.

If the file is connected for unformatted I/O, formatted data transfer is prohibited.


The following example shows formatted, sequential READ statements:

READ (*, '(B)', ADVANCE='NO') C
