That is incorrect, -rowrnks- requires a varlist: see -help varlist-.
So you can type -rowranks(x1 x2 x5 x300000), ...-. Notice, that there
are no commas between the variable names.

The varlist x1-x5 is just a short-cut that is sometimes useful. I
actually hardly ever use it. Instead I tend to make heavy use of the *
and ? characters. Neither shortcut will help you in this case, you'll
just have to explicitly spell the entire list, which is not a problem
just more work.

Hope this helps,
Maarten
