Hi Sergey
>Where did I referer to SYS(3)?
No you didn't, it was why sys(2015) was any different/safer/unsafer than substr(sys(2015), 3). Well what I had wanted to point out is that our programming part of our (atleast a few of our) brain has been tempered to not trust sys(3) and use
substr(sys(2015), 3, 10) instead so I guess we have stuck to it, and refer to it by default.
