structure inside while should work only one time ?

[parthabe]

I can see only a Numeric based CS inside the Bool based outer CS. Am I missing something, or did you mean something different by "Inside the true case is another case structure that should only be true"?

Later it was asked "is it possible to do without incrementing (+1) ", and I took that as meaning that he is looking for a solution that does not require the use of a numeric. Thus I was providing an alternative solution to the original problem.
