That does not trigger recompilation. It's not that useful for switching from debug mode to prodcution. _vfp.startmode is much better for that, you don't even need to change a constant to switch from debug to production. Just don't use it with

Thanks, Olaf. Used correctly it reduces the size of the exe which is what I think Dmitry is after.
