7.2.2 Direct Access READ Statements

Direct access READ statements transfer input data to internal storage from external records accessed under the direct mode of 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 (extu,rec,fmt [,iostat] [,err]) [iolist]

Unformatted

READ (extu,rec [,iostat] [,err]) [iolist]

extu

Is an external unit specifier.

rec

Is a record specifier.

fmt

Is a format specifier.

iostat

Is an I/O status specifier.

err

Is a transfer-of-control specifier.

iolist

Is the I/O-list specifier.

The control-list parameters are extu, rec, fmt, iostat, and err. The I/O list parameter is iolist.
