<> Not sure what you are trying to do. If you want the counter as strings (why would you want that?), you can just say *********** bysort plot: gen bldg=string(_n) *********** -string()- happily accepts -format- as well. -tostring-`s -format()- option accepts _numeric_ formats, as you are moving from numeric to string. If you want to -format- the finished results, do it in a separate line, just as you seem to be implying.
