hi folks,

I'd like to work with completely empty (or nonempty) variables, only (about 1200 to 1300 variables each group of vars).
Is there a way to assure, strings to be included in the `r(varlist)' (of empty vars) if they contain nothing more than the ordinary "." or " " ...?
Using missings, I miss the option trim piasm (as for the quite crude dropmiss).
Code:
missings report, sysmiss min(all obs)
The aim is keep one (or the other) group of vars, run desc, replace clear , and export the resulting metadata "observations" as Excel to easily work on the list of variables including varlab, type andsoforth as "variables" ...

thx a lot
