[JPR] Hi David,
I'm not sure about this topic... About what do you try to demonstrate... > I did it on purpose to see what happens. I'm fanatical about checking > inputs and preconditions and wanted to see what sort of error to trap for. > In many cases, there is no error trapped - it just screws up. Is it a crash test? A kind of stress test? Do you really want to find a way to crash 4D? If yes, I can tell you many ways to crash 4D, or your System, or your HD, or even your computer, beyond any hope of recover... It's like if you test a car, pedal to the metal, and ask what will happen if you close your eyes and turn abruptly the steering wheel. Is it useful? What I said during this training is basically: - Except in very exceptional cases, you do NOT need preemptive, so you can keep your interprocess variables and interface tricks. - If you actually NEED preemptive tasks, then you will develop new programming for that, and then why not do it in a kind of thread-safe programming, just in case... - Any analysis that concludes into a need to synchronize your thread with others is probably wrong somewhere. - You can always try to cheat with 4D, if you like it, but in serious programming, don't try to mess with 4D, for I strongly doubt it will do any good... > I objected to EXECUTE for a very > long time because of this very reason. Unsafe at any speed. That's true. But you know, Life is unsafe at any speed. Why to object to a command? Just don't use it if you do not feel safe with it, and let people willing to use it do it at their own risks. I feel BASE jumping very unsafe, so I don't do it, and I still feel good about people who like it...
