I have a While loop that looks like this:

    Zone1 = ...;
    Zone2 = ...;
    Zone3 = ...;
     ...
    Zone9 = ...;
    a = 1;
    while a <= 9
         TrueOrFalse = Subfunction(strcat('Zone',num2str(a)));
                      %Subfunction outputs 0 or 1
         if TrueOrFalse == 0
              break % end while loop
         end % end if statement
         a = a+1;
    end % end while loop

Now, the problem I'm running into in Debug mode is that the strcat(strings) function is outputting a string that is correct, but it's not calling on the previously established variable or matrix.

What can I do to make that work?

You want to store your zone data in a numeric array or a cell array, and then index it for passing the relevant data item to the sub function.

For numeric data:

 zonesData = [100, 800, 1750] ;
 for k = 1 : length( zonesData )
    isOk = SubFunction( zonesData(k) ) ;
    if ~isOk
        break ;
    end
 end

For other types of data, e.g. strings:

 zonesData = {'USA', 'CH', 'FR'} ;
 for k = 1 : length( zonesData )
    isOk = SubFunction( zonesData{k} ) ;
    if ~isOk
        break ;
    end
 end
