/sys$common/syshlp/helplib.hlb FORTRAN, Statements, NAMELIST  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  Defines a list of variables or array names and associates that list
  with a unique group-name, which is used in the namelist I/O
  statement.

     NAMELIST/grp/nlist[[,]/grp/nlist]...

     group-name  Is a symbolic name.

     nlist       Is the list of (no more than 250) variable
                 or array names, separated by commas, to be
                 associated with the preceding group-name.

  You cannot include array elements, character substrings, records,
  and record fields in a namelist, but you can use namelist I/O to
  assign values to elements of arrays or substrings of character
  variables that appear in namelists.  Dummy arguments can appear in
  a namelist.

  The namelist entities can have any data type and can be explicitly
  or implicitly typed.

  Only the entities specified in the namelist can be read or written
  in namelist I/O.  It is not necessary for the input records in a
  namelist input statement to define every entity in the associated
  namelist.

  The order of entities in the namelist controls the order in which
  the values are written in the namelist output.  Input of namelist
  values can be in any order.

  A variable or an array name can appear in several namelists.
