A first computing device is programmed to perform operations (i) to collect parameter data for use by a remote function, and (ii) to pass information, including the parameter data, to a second computing device. The second computing device is programmed to perform operations (i) to build a stack based on the parameter data, (ii) to use the information to locate code for the function on the second computing device, (iii) to execute the code for the function on the second computing device, where the function uses the parameter data on the stack, (iv) to obtain output values from execution of the code for the function, and (v) to pass parameter data, including the output values, to the first computing device.
