GBeebe,
Since you also program in Linux, let me ask you an off-topic question. Is there a way (other than WINE or something similar) to use PureForm in Linux? The only download I have seen for PureForm is a Windows .EXE.
Can default for a Structure be a null?
Re: Can default for a Structure be a null?
There is no way to natively run a Windows EXE in Linux without the assistance of WINE or the likes. Another good alternative is VirtualBox. You can use it to install and run Windows on a "virtual computer" running in Linux. Then you'll have a window with a Windows desktop on. It's pretty neat and fun to experiment with. I'd do it, 'cept my XP key won't work without me calling them and they told me they wouldn't let it work because of how I was installing it.
