How to set a string as a CODE in script file?

Legend CODE
Sum SU
Difference DI
How can I set this code(SU and DI) so that the user will only input these codes and will work the other lines?

I am not certain what you are actually asking.
If you want the user to enter specific values and assign them in the code to specific variables, I prefer using the inputdlg function. That gives the script control of the variable assignments.

validcodes = {'SU', 'DI'};
while true
choice = input('Enter a code: ', 's');
if strcmpi(choice, validcodes); break; end
fprintf('Bad code, try again\n');
end
But have you considered using menu() ?
