Using OR to check is a value is true

I wanted to make a function that should say IF A1 is equal to 1 or 2 or 3 then TRUE else FALSE. I thought I could do that through

=IF(A1=OR(1;2;3);TRUE;FALSE) but that didn't work. Now, I understand that it should have said

=IF(OR(A1=1;A1=2;A1=3);TRUE;FALSE), but I would have preferred a simpler approach. Is there a way to do something like in the first approach?

/Møller

=IF(MATCH(A1;!!!Insert list or range here"";0);TRUE;FALSE)

is one of your options

Neat. Thanks.
