    %% Return Values as Handles
% Provide the system to |find_system| as a handle. Search for block dialog box parameters with a value of |0|. If you make multiple calls to |get_param| for the same block, then using the block handle is more efficient than specifying the full block path as a character vector.

load_system('vdp');
sys = get_param('vdp','Handle');
find_system(sys,'BlockDialogParams','0')
