st: Confirm existence of a variable(s) with wildcards in the variable name

Hi,
I'm trying to unabbreviate a variable list that contains a wildcard
and then keep those variables, if the variable(s) exist. From my
understanding, the 'if' option in STATA's 'keep' and 'drop' commands
only act on observations, not on variables.
I'm trying code, unsuccessfully, along the lines of...
capture confirm unab new: varia*
if(_rc==0){
unab new: varia*
local newlist `new'
}
keep `newlist'
Any help would be much appreciated.
