Namelist

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

 Namelist I/O statements do not specify a format (FMT=) in the
 control list (clist).

 Namelist sequential READ:

    READ (UNIT=u,NML=nml[,IOSTAT=ios][,ERR=err][,END=end]) 
    READ n

 Namelist sequential WRITE:

   WRITE (UNIT=u,NML=nml[,IOSTAT=ios][,ERR=err]) 

 Comments (beginning with !  only) can appear anywhere in namelist
 input.  The comment extends to the end of the source line.
