Hi everyone, Case: In a given situation I want to add 1 to an specified integer. Something like this: integer atbat, RBIplayer1, RBIplayer2, RBIplayer3.....RBIplayer 10, etc. if X > 0 then if atbat = player1 then RBIplayer1 = RBIplayer1 + 1 end if if atbat = player2 then RBIplayer2 = RBIplayer2 + 1 end if .... if atbat = player10 then RBIplayer10 = RBIplayer10 + 1 end if end if Is it possible to simplify it to something like this: if X > 0 then RBI[atbat] = RBI[atbat] + 1 end if Bye, Jasper.

If you're feeling especially reckless, you can also write: RBI[atbat] += (X > 0) -- David Cuny

Hi David, I tried RBI[atbat] = RBI[atbat] + 1 and it didn't work. I thought I was using a wrong statement. I can't give you the error message right now because I'm not behind the computer on which I'm developing my program. Can I conclude from your reaction that I'm on the right way? (For this case then ) Bye, Jasper.

This is a classic use of sequences. Remember that a sequence can be used to implement an array. In this case a list of scores. He is a bit of code to demonstrate it. ---------- sequence RBI constant MAXPLAYERS = 10 integer atbat . . . -- Initialise the scores RBI = repeat(0, MAXPLAYERS) . . . -- Increase score if X > 0 then if atbat > 0 and atbat <= MAXPLAYERS then RBI[atbat] += 1 else printf(1, "Logic error: 'atbat' = %d\n", atbat) end if end if ------------ Derek.

Thanks, I haven't tried it yet but I think an array is exactly the answer on my question. Jasper.

One thing that can be really helpful is to use Euphoria's trace facility. I've found it invaluable for debugging code. > Can I conclude from your reaction that I'm > on the right way? (For this case then ) Yes. Good luck! -- David Cuny
