    %% macro mode eliminates the overhead of functions calls

    %% function mode gives code that is easier to debug

%% Allowed sizes for production target used some places to 
%% reproduce the data type propagation steps INTERNAL to a block.
%% In particular, fixed-point multiplication and division
%% routines uses this information to determine temporary
%% data types when dealing with non-zero bias.
%% Piping the information from Simulink into the RTW file and 
%% trying to distribute it to TLC utilities when and where
%% needed would be very expensive.
