Ok. What you have is quite good. You read the data and you write them.
The remaining part is to sort them. Your procedure check is a good
starting point. You check two number and if they are in the wrong order
you swap them. So do this not only for no(1) and no(2) but do it for all
numbers until they are ascending. For more information on sorting
algorithms you should look into the literature, e.g. Wirth's "Algorithm
and datastructures".
