10.3.2 Forms for Direct-Access READ Statements

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:

Formatted

 READ (eunit, format, rec [,iostat] [,err]) [io-list]

Unformatted

 READ (eunit, rec [,iostat] [,err]) [io-list]

eunit

Is an external unit specifier ([UNIT=]io-unit).

format

Is a format specifier ([FMT=]format). It must not be an asterisk (*).

rec

Is a record specifier (REC=r).

iostat

Is a status specifier (IOSTAT=i-var).

err

Is a branch specifier (ERR=label) if an error condition occurs.

io-list

Is an I/O list.
