Unless I'm misunderstanding, then my code will do it for you. Calling your variables v1 to v50: foreach v1 of varlist v4-v50 { foreach v2 of varlist v1 v2 v3 { tab `v2' if `v1'==. } } It is not one line, but it is pretty quick and easy to do. If you actually want the cases listed, rather than tabulated, just substitute "list" for "tab" above. If you want to list all three of the variables v1 v2 v3, then: foreach v1 of varlist v4-v50 { list v1 v2 v3 if `v1'==. } --Nick Winter ----------------------------------------------------------- Nicholas Winter, Ph.D. P 202.939.5343 Policy Studies Associates F 202.939.5732 1718 Connecticut Avenue, NW nwinter@policystudies.com Washington, DC 20009-1148 www.policystudies.com ----------------------------------------------------------- > -----Original Message----- > From: Banya, Winston [mailto:w.banya@ic.ac.uk] > Sent: Monday, September 23, 2002 11:20 AM > To: 'statalist@hsphsun2.harvard.edu' > Subject: st: RE: RE: tabulation of variables > > > Thanks Nick but I am not sure if I am getting it right.
