No, change it to INTEGER.

Use the VFP BITTEST() function to test the 3rd bit from right.

>How can get the return value in VFP ?

I already posted the call for this function in a pervious message.

As Ed said, you should dig a little on memory management/pointers (syntax also) in C or hire somebody who knows these issues. Even with Ed's CLSHEAP class or my Pointers class or any other similar software, you still have to understand the basics of memory management and pointers in C.

For the above "if", the equiv. in VFP would be:

if BITTEST(ASC(LEFT(lcResponse, 1)), 2)
