st: mata's st_data

I was wondering if there is a way to use wildcard for variable names
in mata's "st_data" function. I have a large number of variables, like
US_ctry, UK_ctry, etc, all of which could be defined in Stata as
"*ctry".

But when I try the following in mata:
A  =  st_data(.,(“*ctry”)).

I get the warning:

*ctry invalid name

The (tedious) alternative is: A  =  st_data(.,(“US_ctry”, “UK_ctry")

Any suggestion would be appreciated, because the number of variables
are too many.

Joe
