Optimization Levels

With higher levels of optimization, you cannot change variables and might not be able to view the actual value of a variable during debugging. When you are debugging, set the optimization level to 10 (*NONE). This provides the lowest level of performance for the procedures in the module but allows you to accurately display and change variables. After you have completed your debugging, set the optimization level to 30 (*FULL) or 40. This provides the highest level of performance for the procedures in the module.
