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