Direct-access READ statements transfer input data from external records with direct access. (The attributes of a direct-access file are established by the OPEN statement.)
A direct-access READ statement can be formatted or unformatted, and takes one of the following forms:
READ (eunit, format, rec [, asynchronous] [, id] [, pos] [, iostat] [, err]) [io-list]
READ (eunit, rec [, asynchronous] [, id] [, pos] [, iostat] [, err]) [io-list]
