Ben,

To provide a practical answer I would need to know more about what you are actually doing. I assumed your data _null_ examples were just a way to look at string scanning. What is your real task? What do you mean "the demension of array is going to be varied from 2 to 50"? Are you actually creating a SAS dataset, or are your "putting" values to a CSV file, or ...?

If you provide more context, you will get answers more tailored to your needs.
