ds *3, not 

If no variables match the pattern, this will return an 
error; otherwise -not- specifies return of the complement 
in `r(varlist)'. 

-ds- is currently undocumented (meaning, there is no 
manual entry), but the help and the .ado are there 
for you to use. 

If -ds- didn't exist, this would be a three-step 

unab not : *3 
unab all : _all 
local all : list all - not 

and in general that should be more efficient, not 
that you would normally notice. See
help for -macrolists- and -unab-.
