G'day madM,

I provided that code in "Re: printf matrix". This was in response to your post, "printf matrix", where the largest numerical datum contained two digits.

If your numerical data may now contain up to four digits (i.e. 2 digits more than previously), how is it possible that you cannot modify the format to accommodate this?

I suggest you go back to my previous reply and read the documentation regarding formats that I linked to. If, after that, you still can't work it out, please post again specifying exactly the difficulty you're having adding 2 to a number.
