You can do a variety of things in the !bet section depending on how you want to do this and how many bets you want to handle at once.
If you only want one bet per nick, you could change your variables to %whatever. $+ $nick and then to use the variable, you'd use $($+(%,whatever,$nick),2) . You can then easily unset all bets by just unsetting all matching variables... /unset %whatever*
If you want multiple bets per nick or expect to have a lot of bets rather than only a handful at a time, then you can store the bets in a file or a hash table. I'd probably recommend a hash table. Especially if you're not planning to save the bets for use later on and want it to just clear out each time you start mIRC. If you do a hash table, you can do the same kind of thing for storing the data. First, create the table /hmake bets . Then, when bets are done, add the bets to the table. If you only want one bet per nick, you can add them as //hadd bets $nick %roller1 %roller2 %bet . If you want multiple bets from the same person, you can use something other than the nick for the bet name (it's up to you) and then include the $nick as part of the data value. Then just use $hget() and $gettok() to retrieve the data.
You can use /help on any of the commands for more details and examples. That should get you a good start on what you need.
