I have a set of variables. And for different scenarios, I would like to use a different set. So I was wondering if there is a way of doing so without using the `if-else` statement? Below is what I am trying to achieve using the `if-else` approach:

```
if(broker=="A"){
  brokeragefutures=aaaa
  brokerageoptions=bbbb
  STT=cccc

} 
else if(broker=="B"){
  brokeragefutures=xxxx
  brokerageoptions=yyyy
  STT=zzzz
}
  ....
  ....

  ....
}

```

So in the end, I would just use the broker name and the variables will automatically be used for my computations. This would make trying different scenarios very easy. 

My question is, is there a more efficient way of doing this, than by using the `if-else` loop?

Thanks.
