Skipping part of code

I've wrote a script that can be splitted in independent parts. Sometimes I don't want to execute all of them, and so I'm using on each part of the script a simple check of the type
if flag
% do what you have to do
end
where flag can be zero (if I want to skip the current part) or one (if I want to execute the current part).
This trick works fine but is pretty annoying because when I set a zero flag the analyzer returns a warning. I don't want suppress such warning of the analyzer, so I'm looking for a new solution (entirely procedural) that does not generate any warning.

putting the else statement still produces the warning. But good to know with the %#ok comment

You could do it with a while loop. This does not produce a warning. And don't forget to put in the break statement at the end of the loop 😉
flag = 0;
while flag
% do what you have to do
a = 123
break
end
disp('end')
end

The other way that fools the code analyzer is to insert one level of indirection...the following doesn't generate the warning whether DBG is True or False...
DEBUGFLAG=[True|False]; % set the state desired
flag=DEBUGFLAG; % assign state to the logic variable..
....
if flag
% do what you have to do
end
The possible problem with the above is, of course, if you have multiple sections to set independently.
I'd probably just choose to ignore the warnings for a case like this since know what it is am trying to do.

Ah yes, the technique of baffling the analyzer with bovine excrement ;-)
