Classdata - Proc Summary

[SimonMorehen]

Hello,

I've recently discovered the classdata option which seems very useful but I am experiencing some very odd results with it.

Can anyone explain the following please?  Why doesn't the whole of classdata2 get read in?  And why is the output dataset empty?!  Is there a maximum number of observations in the classdata data set?

Thanks,

Simon.

what does classdata2 look like? Can you show a short summary?

If it looks correct, it sounds like a tech support question to me.
