List-Directed

 List-directed I/O statements are similar to formatted statements in
 function, but control the translation of data through data types
 instead of explicit format specifiers.

 List-directed I/O statements specify a format (FMT=) in the control
 list (clist).  Other "clist" elements are required depending on the
 type of access.

 List-directed sequential READ:

   READ (UNIT=u,FMT=*[,IOSTAT=ios][,ERR=err][,END=end]) [iolist]
   READ * [,iolist]

 List-directed internal READ

   READ (UNIT=u,FMT=*[,IOSTAT=ios][,ERR=err][,END=end]) [iolist]

 List-directed sequential WRITE

   WRITE (UNIT=u,FMT=*[,IOSTAT=ios][,ERR=err]) [iolist]

 List-directed internal WRITE

   WRITE (UNIT=u,FMT=*[,IOSTAT=ios][,ERR=err]) [iolist]
