increment in While Controller

[Aliaksandr Yermakovich]

Hi All,

Could somebody tell me, how too create and use a variable and increase it each 
loop in While Controller? Like:

while ( foo=="true")
          i++;
);

I've got a number of pages, (like question_1.aspx, question_2.aspx and so on) 
which have a number at the end. Number gets increased and can dynamically 
change (sometimes there are 11 pages, and another time 18). I'd like to go 
through them in while cycle, but don't' know how to get this number increased 
each loop.

Thanks.

Best Regards,
Alex
