extracting row array
Solved!

In your program, the outer For loop will return a value of 79 which you are comparing it with 2 (i hope you are trying to get the 3rd row) in the next while loop. That's the error. Why you don't want to use an index array? Ok as per your method try the attached(change the while loop only). Post back.
(Even as an "advanced" beginner, you should never add a new question to an existing thread that is marked as solved.)
Here's one possible solutions. I can think of a dozen other ways to do this.
The primitive inside the loop is "initialize array", the last function is "reshape arrray". you should be able to figure out the rest. Try it!
Since the question was "for example 3 times", I would assume the number of repetitions should be a control.
Building the array in a shift register is more compact, but I worried about possibly memory re-allocations. In principle, the compiler should be able to figure out the final size in your code from first principles, but I am actually not sure that it does in a case like that. 😉 Would be worth investigating.
In my code, the final size of the 2D array is know when the loop starts, so the full array size will be pre-allocated. (The reshape function requires another allocation). Since this is for display on a front panel, I assume that the arrays are small and we don't have to worry about performance. 😉
