Select with multiple Variables

Hello

I got a question. Is there any other way to do Select function:

We got 5 different vars: $1=true or false, $2=true or false and $3=true or fallse

And now the select function

Select
Case $1=true and $2=true and $3=true
 ..do something..
Case $1=false and $2=false and $3=false
 ..do something..

So with three variables we need to write 8 different combinations. Thats not really hard, but when we got 8 different variables we need to make 256 Cases. Is there any easier way to do such a thing?

Like for example:

Case $1=true and ($2=True or False)

Any ideas?
