Hi, I believe macro list is the best way then. I was wondering if
there existed some wildcard syntax similar to what I suggested. I
guess not. Thanks Kit and Sergio for your prompt replies.

You can use the -unab- command (or tsunab if you are using time-series
operators), mixed with a macro function:
An example could be:
unab allvars : int_*
unab excludedvars : int_abc int_xyz
local selected : list allvars - excluded
And then you use the local macro -selected- like this:
reg y x1 x2 `selected'
You will see that the results do the same as (int_* - int_abc - int_xyz)
Cheers,
Sergio
PS: Its not in one line, but after you create the macro you can use it
everywhere, from summ to xtprobit

Kelvin wants to use a wildcard list and remove a couple of elements
from the list. The list macro functions are useful in that regard:
webuse auto,clear
tab rep78,g(RR)
unab rnames: RR*
local dontwant RR2 RR4
local rnames1 : list rnames - dontwant
di "`rnames1'"
su `rnames1'
