Hi, All

I have a dataset with the structure like this:

pid   var1   var2   var3   var4   var5
---------------------------------------
111   aaa    bbb
222          ccc           ddd
333
444   aaa
555                 eee
666

I want to pick up the subjects with any of var1-var5 have value. Like this

pid
----
111
222
444
555

How can I do this in some simple way, since I actually have 20 var. If I use
if... then... that is really a lot work to do.
Thanks

Jane
