<> Let`s add that -ssc d findname- is a user-written command by Nick Cox, and a very recent addition to ssc. If Eduardo wants to -replace- all missings with zero, regardless of variable type, he can of course say: ************* clear* set obs 10 gen x=1 replace x=. in 2/3 gen y=2 gen z=3 replace z=. in 3/5 foreach var of varlist _all{ di in r "Now at variable `var'" replace `var'=0 if `var'==. } ************* HTH Martin -----Ursprüngliche Nachricht----- Von: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] Im Auftrag von Neil Shephard Gesendet: Dienstag, 6.
