Is there a command that will give me the proportion of the time a

weights. I'm looking for something like -tabcond-, from SSC, but
that returns proportions as well as counts.
One option would be to -generate- a dummy equal to 1 when my
variable is equal to my value and zero otherwise and then to use -
svy: mean-, but I would prefer something that can be done in one
line (and without generating a new variable). My variable is
continuous, so I don't want to -svy: tab- the whole thing.
