Well, since you can't push back the pointer to your data, try the following: (Assuming that the following occurs: 1) You know how many rows you want to return at the time you are returning. 2) you are not returning too many rows or the rows are not too big. 3) you know what the data set will contain. (You can get around this too ) ) Push the data on to the stack in reverse column order. (You want A B C so push C B A) Then at the end push the number of rows (LONG) on the stack. Pop the number of returned rows, and enter a for loop poping data off. In my drug induced foggy memory, I believe that if you do not clear the stack of data, you may run in to problems.
