multiple case

hi all
im working in tcsh shell.
In sh shell i write for example:

case in $www
1 | 2 | 3)
arguments;;
4 | 5 | 6)
arguments;;
esac

can anybody tell me the equivalent to tcsh of
1 | 2 | 3)?

Please see the tcsh man page. Excerpt:

If I use "?" as a case label, what does it mean?

For Example:

case $choice in
1)
.....;;
2)
.....;;
?)
.....;;
esac

Here what does "?" in case label mean?
