>I am trying to make a call to a function within a dll from VFP 6.0. The dll is written in C++. The function returns an integer value flagging whether the function executed successfully or not: 0 for success and non zero for failure. If executed successfully then one of the arguments contains the result set that I need to use. How do I access that value??

Maybe try

x=v_o_d(outvin, @options)
