B.8 Alternative Syntax for a Record Specifier

In Compaq Fortran, you can specify the following form for a record specifier in an I/O control list:

'r

r
Is a numeric expression with a value that represents the position of the record to be accessed using direct access I/O.

The value must be greater than or equal to 1, and less than or equal to the maximum number of records allowed in the file. If necessary, a record number is converted to integer data type before being used.

If this nonkeyword form is used in an I/O control list, it must immediately follow the nonkeyword form of the io-unit specifier.
