- Accessing Files Using the `nxm.` ("dot") Syntax:
  - Files can also be accessed via their package name.

        nM> plot nxm.sys.dat.world.prm
        <Plots the world.prm file in the DAT area of SYS>

  - This feature is highly recommended!
    - This is a very portable way to access files.
    - Use of this syntax is common in tests cases.
    - This is the easiest way of specifying a file in a specific option tree.

Java Experts Take Note:
This way of referring to a file is based on the Java package naming scheme. The only differences being that it must start with "`nxm.`" and it has a file extension at the end (since not all files have a .class extension). Because of this file extension, NeXtMidas enforces a strict ordering of: nxm.<option_tree>.<area>.<file_name>.<file_extension>
