Section 13,44: NAMELIST

 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 /group-name/nlist[[,]/group-name/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, pointers,
 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.
