>>>>>Daniel -- I am not aware of a native function to handle this, but one note that may help: your code will run more quickly if you declare a local array, do all the adding into that array, and then coppy that array at the end into the form level array. VFP is relatively slow at moving data into and out of form-property arrays, at least compared to local arrays. Even the later ACOPY probably won't cost you as much time as you will save with a local array.

But in this case, a one-shot deal, it's probably a wasted effort. Afterall, you can only split a frog hair so fine. :)

Ahh. That's very different. What you're actually measuring there is the time to expand the array's size, not just populating it. But even in that case, you'd still spend a similar amount of time expanding the "local" array vs the "property" one, even if it is faster. Maybe quicker to have a "full sized" array, populate it, and then cut it back to the "actual size" at the end?
