NAMELIST Statement

Description

The NAMELIST statement specifies a list of variables that can be referred to by one name for the purpose of performing input/output.

Syntax
 

     NAMELIST /name/ group [[,] /name/ group] ...
 Where:
 

     

         name is the name of a namelist group.
     

         group is a list of variable names.
 
 

Remarks

A name in a group must not be the name of an array dummy argument with a non-constant bound, a variable with a non-constant character length, an automatic object, a pointer, a variable of a type that has an ultimate component that is a pointer, or an allocatable array.

If a name has the public attribute, no item in group can have the PRIVATE attribute.

The order in which the variables appear in a NAMELIST statement determines the order in which the variables' values will appear on output.

Example
       real :: a,b
       integer :: i,j
       namelist /input/ a,b,i,j
       open(10,file='data.dat')
       read(10,nml=input)
       write(*,nml=input)
       close(10)
       end
        
       ! namelist data file
       &input
       b=12.3
       i=4
       a=13.2
       j=12
