How do I refer to an item generically?

[Kaveh Bazargan]

Here is a code I have to delete all empty groups:

repeat with i = 1 to the number of groups
if the number of btns of group i is 0 and the number of flds of group i \
is 0 and the number of sbs of group i is 0 then
delete group i
end if

If there a shorter way of saying this?
