 Message        Part or all of the non-scalar variable
                "<var>"<declared in> is fetched but not
                initialized<inlineinfo>.  And there may be other such
                fetches of this variable that have not been reported
                in this compilation.

 Description    A non-scalar variable has had its value used and some
                or all of the variable has not been given a value.
                This might not have been what you intended.  The
                algorithms that detect this situation only report it
                once for a given variable, and not necessarily at the
                first use of the uninitialized value.

 User Action    Provide the variable with a value before the variable
                is used.  If you only provide a value for the use
                reported here, you may find that when you recompile
                your program another uninitialized use is detected.
                It is best to initialize variables as close as
                possible to the point of declaration.
