The easiest way is with a program like Stat/Transfer; well worth the money if you are going to be doing this a lot, as it is easy and will preserve your labels and handle quirky differences in the way the two programs handle things (e.g. missing data). (But check to make sure you like the way it handles quirky differences, e.g. there are a couple of ways of handling missing data conversions.)

Alternatively, -findit spss- points to routines like -outdat- that will make the conversion one way or another.

I also have fairly good luck just cutting and pasting from SPSS's data editor to Stata's; I'm not sure that you can count on that to handle all types of conversions though.

You can also do "Save as" in SPSS, choosing a format that Stata can import. Not sure which options are easiest.


3) I am using weights:
so generally I write

tabstat variable [aweight=weight] by variable....

Is there any way I can use weights without including
it in the tabstat command? I want to run a bunch of
summary table, would like to use weights for all of
them.
I suspect not, but I am curious too. A difference that strikes me between SPSS and Stata is that, in SPSS, I can specify weights or filters (i.e. temporary sample selections) and they continue to hold until I tell SPSS otherwise; in Stata I have to keep on specifying the weights or filters with every command.
