>Couple questions as to what this procedure is doing. It works, but I'm not sure about the "@strData" in the GETDATA. Is that a variable by reference? So that after GETDATE runs, the value of strData is returned? Also, why the "SPACE(256)" line? Is it to define it as a string, or to define the length, or both? It works with strings much larger than 256, so I'm just curious what the purpose is. Thanks!

Yes, this is a variable passed by reference so the procedure would see its updated value after the call. I think it would work even if you set it to ""
