WRITE

 Transfers data from internal storage to user-specified external
 logical units (such as disks, printers, terminals, and pipes) or
 internal files.

 The meanings of the symbolic abbreviations used to represent the
 parameters in the WRITE statement syntax are as follows:

    extu    Is the logical unit or internal file optionally 
    or      prefaced by UNIT=.  UNIT= is required if unit is
    intu    not the first element in the clist.

    fmt     Specifies whether formatting is to be used for data 
            editing, and if it is, the format specification or an 
            asterisk (*) to indicate list-directed formatting. 
            The "fmt" is optionally prefaced by FMT=, if "fmt"
            is the second parameter in the clist and the first 
            parameter is a logical or internal unit specifier 
            without the optional keyword UNIT=.

    nml     Is the namelist group specification for namelist I/O. 
            Optionally prefaced by NML=.  NML= is required if 
            namelist is not the second I/O specifier.

    rec     Is the cell number of a record to be accessed directly.
            Optionally prefaced by REC= or by an apostrophe (').

    iostat  Is the name of a variable to contain the completion 
            status of the I/O operation. Prefaced by IOSTAT=.

    err     Is the label of a statement to which control is 
            transferred in the event of an error. Prefaced by 
            ERR=.

    end     Is the label of a statement to which control is 
            transferred in the event of an end of file. Prefaced 
            by END=.

    adv     Specifies advancing (ADVANCE='YES') or nonadvancing 
            input (ADVANCE='NO').  The default is 'YES'.

    iolist  Are the names of the variables, arrays, array elements, 
            or character substrings from which or to which data 
            will be transferred.  Optionally an implied-DO list.

 The control-list parameters are "extu" (or "intu"), "fmt", "nml",
 "rec", "iostat", "err", "end", and "adv".  The I/O list parameter
 is "iolist".
