The usual technique is to declare the configuration variables at the

If your variables are strictly internal and by no means might be ever

If I'm reading this right then it looks like you're trying to

Symbolic references are incredibly danger

Hi, How do I name this variable correctly, @{bet$random_bet_position);
With regards to the script below, @selected_bet is suppose to select either
@bet1, @bet2 or @bet3 depending on the chosen number held by
$random_bet_position, so how do I do this? Thanks
@bet1 = (0,0,0,0);
@bet2 = (0,0,0,1)

Also, if I may, a word about your code: You keep testing some variables for
definedness, but don't do anything when they are undefined, so you end up
piling on checks. Wouldn't it be simpler to return early? For instance, if
$date isn't defined, nothing else
