Subject:      Counting Unique Occurrences Across Variables
Content-Type: text/plain; charset="iso-8859-1"

The COUNT command counts the number of occurrences across variables. Is
there a command that reports the number of unique occurrence across
variables. An example will be demonstrate what I'm after.

V1  V2   V3         Desired Answer

1     2     3                3
1     2     1                2      i.e. the '1' is only counted once.

Any suggestions will be appreciated.
