Hi Daniel, Thanks for your help. Unfortunately, I cannot get your scripts to work. It looks like you enter a string of options when you run the script. Do you have an example? Maybe this is really dumb, but your assembler code has #include and #define statements that create errors with clpru. Is there an option I am missing? I can use .asg instead of #define, but I am not sure what to use instead of #include.
