## 10.5.1 Forms for Sequential WRITE Statements

Sequential WRITE statements transfer output data to external sequential access records. The statements can be formatted by using format specifiers (which can use list-directed formatting) or namelist specifiers (for namelist formatting), or they can be unformatted.

A sequential WRITE statement takes one of the following forms:

  Formatted:
  WRITE (eunit, format [, advance] [, iostat] [, err]) [io-list]
  Formatted - List-Directed:
  WRITE (eunit, * [, iostat] [, err]) [io-list]
  Formatted - Namelist:
  WRITE (eunit, nml-group [, iostat] [, err])
  Unformatted:
  WRITE (eunit [, iostat] [, err]) [io-list]
  eunit
  Is an external unit specifier ([UNIT=]io-unit).
  format
  Is a format specifier ([FMT=]format).
  advance
  Is an advance specifier (ADVANCE=c-expr). If the value of c-expr is 'YES', the statement uses advancing output; if the value is 'NO', the statement uses nonadvancing output. The default value is 'YES'.
  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.
  *
  Is the format specifier indicating list-directed formatting. (It can also be specified as FMT=*.)
  nml-group
  Is a namelist specifier ([NML=]group) indicating namelist formatting.
