Hi,

I tried to write a simple addition logic in DLL Maker. When I define dllcommand3 as a double, the return value is correct,

but if I define dllcommand3 as int, the return value becomes 0.

What is the reason, thank you !

Software Version:

FlexSim 18.1.1

FlexSim node function bindings expect the function to return either a double or a Variant.

FlexSim stores numbers in double format. Just return a double, as in your original screenshot.

If you want to return a value that isn't a number, such as a string, have your function return a Variant.
