Subject: Re: "or" and "and" -- still problems, brackets don't work

Thanks for help!

The problem is that 3 or's don't work:

?> st = 1
=> 1
>>      if st != 2 or st !=  5 or st !=  10 then ; st = 1 ; end
=> 1
>>
?> st = 2
=> 2
>>      if st != 2 or st !=  5 or st !=  10 then ; st = 1 ; end
=> 1
>>
?> st = 2
=> 2
>>      if st != 2 or st !=  5 or st !=  10 then ; st = 1 ; end
=> 1
>> st = 5
=> 5
>>      if st != 2 or st !=  5 or st !=  10 then ; st = 1 ; end
=> 1
>> st = 10
=> 10
>>      if st != 2 or st !=  5 or st !=  10 then ; st = 1 ; end
=> 1

Or with extra brackets:

>> if (st != 2) or (st != 5) or (st != 10) then ; st = 1 ; end
=> 1

Hopefully the "include' option works fine and is beautiful, that's a
great example of simplicity of Ruby I'm getting to appreciate.


And about the brackets, Max Williams wrote, it doesn't work either. I
tried if before. I also know the difference on "and" and "&&", I
revived some articles on that while looking for some info.
