The NAMELIST statement specifies a list of variables that can be referred to by one name for the purpose of performing input/output.
SyntaxNAMELIST /name/ group [[,] /name/ group] ...Where:
name is the name of a namelist group.
group is a list of variable names.
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.
