des, varlist
local myvars=r(varlist)
dis "`myvars'"
This produces a macro with all variables names. You can then extract the last one.
However if there are too many variables this trick will not work. 

This is a FAQ. The reason why it won't work with many variables is that you have used an equals sign in the local statement. That truncates the result to 244 bytes if it is longer than that. Do not use an equals sign in this context unless you are trying to do arithmetic.
