+ function and its caller. If a variable is declared llooccaall, the vari-
+ able's visible scope is restricted to that function and its children
+ (including the functions it calls). Local variables "shadow" variables
+ with the same name declared at previous scopes. For instance, a local
+ variable declared in a function hides a global variable of the same
+ name: references and assignments refer to the local variable, leaving
+ the global variable unmodified. When the function returns, the global
+ variable is once again visible.
+
+ The shell uses _d_y_n_a_m_i_c _s_c_o_p_i_n_g to control a variable's visibility
+ within functions. With dynamic scoping, visible variables and their
+ values are a result of the sequence of function calls that caused exe-
+ cution to reach the current function. The value of a variable that a
+ function sees depends on its value within its caller, if any, whether
+ that caller is the "global" scope or another shell function. This is
+ also the value that a local variable declaration "shadows", and the
+ value that is restored when the function returns.
+
+ For example, if a variable _v_a_r is declared as local in function _f_u_n_c_1,
+ and _f_u_n_c_1 calls another function _f_u_n_c_2, references to _v_a_r made from

+FUNC1, and FUNC1 calls another function FUNC2, references to VAR made
+from within FUNC2 will resolve to the local variable VAR from FUNC1,

Variables local to the function may be declared with the

+the function and the commands it invokes. This is particularly
+important when a shell function calls other functions.
+
+Local variables "shadow" variables with the same name declared at
+previous scopes. For instance, a local variable declared in a function
+hides a global variable of the same name: references and assignments
+refer to the local variable, leaving the global variable unmodified.
+When the function returns, the global variable is once again visible.
+
+The shell uses @var{dynamic scoping} to control a variable's visibility
+within functions.
+With dynamic scoping, visible variables and their values
+are a result of the sequence of function calls that caused execution
+to reach the current function.
+The value of a variable that a function sees depends
+on its value within its caller, if any, whether that caller is
+the "global" scope or another shell function.
+This is also the value that a local variable
+declaration "shadows", and the value that is restored when the function
+returns.
+
+For example, if a variable @var{var} is declared as local in function
+@var{func1}, and @var{func1} calls another function @var{func2},
+references to @var{var} made from within @var{func2} will resolve to the
+local variable @var{var} from @var{func1}, shadowing any global variable
+named @var{var}.
+
+The following script demonstrates this behavior.
+When executed, the script displays
+
+@example
+In func2, var = func1 local
+@end example
+
+@example
+func1()
+@{
+ local var='func1 local'
+ func2
+@}
+
+func2()
+@{
+ echo "In func2, var = $var"
+@}
+
+var=global
+func1
+@end example
+
+The @code{unset} builtin also acts using the same dynamic scope: if a
+variable is local to the current scope, @code{unset} will unset it;
+otherwise the unset will refer to the variable found in any calling scope
+as described above.
+If a variable at the local scope is unset, it will remain so
+until it is reset in that scope or until the function returns.
+If the unset acts on a variable at a previous scope, any instance of a
+variable with that name that had been shadowed will become visible.
