strcat(strings) to call a variable or matrix

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
