    (Applies to Ada programs.) Controls whether the debugger loads
    into the RST the symbol records of a module that is related to a
    specified module through a with-clause or subunit relationship.
    Once loaded, you can reference names declared in related modules
    within debugger commands exactly as you reference them within the
    Ada source code.
