UNINIT1

Message        The 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 variable's value has been used without being set.
               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.
