%GCB Get the full block path name of the current Simulink block.
%   GCB returns the full block path name of the current block in the current
%   system.  During editing, the current block is the one most recently
%   clicked upon.  During simulation of a system containing S-function
%   blocks, the current block is the S-function block currently executing
%   its corresponding MATLAB function.  During callbacks, the current block
%   is the one whose callback is being executed.  During evaluation of the
%   MaskInitialization string, the current block is the one whose mask is
%   being evaluated.
%   
%   GCB('SYS') returns the full block path name of the current block in the
%   specified system.
