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.
