evalc() the program and use text processing techniques to locate the display of "b" and print it out.

Pls use this program. I want to see the result of "b" part only. I will click on b part and run the program.

t = textscan(evalc(sprintf('%s\n', '%%', 'a=5; disp(5)', '%%', 'b=6; disp(b)', '%%', 'c=55; disp(c)')),'%s');
The b part is then
t{1}{2}
However, considering you have put the %% there, possibly the answer you are really looking for is this:
Click on the part you want executed. Right-click and select "execute cell"
