st: storing values from within "by varname :" command

["Andrey V. Ivanov" <aivanov@rumms.uni-mannheim.de>]

Hello.

I have a dataset of individuals (and their characteristics) that belong 
to some groups and live in different regions.

I would like to be able to extract frequencies of individuals by group 
and region and store these frequencies in a different dataset, ultimately.

so, I have the following code:

by region group : count (if...)

and now I want this to be stored in a special matrix that has a vector 
of group name, a vector of regions, and the vector of the result of the 
"count" command.

I know I can bypass all this if I collapse the dataset using the "count" 
option.

But, my question is more general: it is about storing the output of some 
command inside the "by varname :" construct.

Thanks

andrey
