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.
