I think so too that something does not work with your code - I do not know
why
but the code by Philipp Rehm works:
tab x, gen(yf)
ds yf*
di "`r(varlist)'"
local vars = "`r(varlist)'"
sum `vars'

Re: st: RE: simple programming question relating to lists
No, this does not work.
If I do this and type, for instance,
sum `vars'
I get the message
"yf. invalid name"
