Bill, This shouldn't happen as far as I know....even if it was trying to show you the source code for the operation (which comes from the MSL library), it should simply step into it just fine without the window popping up. I ran a quick test where the variable "step" was an integer just to check it out and it worked just fine on R5.0.2. Short term just to get the error to go away, you might try deleting your MSL library that is included in your project and go to the MSL project and rebuild it and include the new library in your project (maybe your MSL library got corrupted somehow). You can find the project for the MSL library at: {install directory}\M56800 Support\msl\Msl_c\DSP_56800\Project\ Hope this info helps!
