A commandgroup is one of those things that seemed like a good idea at the time. I think it's in VFP for two reasons:
1) to aid in conversion from FP2.x. Every button in an FP2.x screen turns into a commandgroup in a form.
2) because VB had them. And that's because VB didn't have inheritance.
Bottom line. I've never found a reason to use a commandgroup rather than simply putting buttons in a container.
