variable question

[smokinace]

what is the hierarchy of variable creation?

if i create a variable inside an if statement using "my" is that variable only good in the if statement?
example

if (condition) {
my ($var1, $var2);
}

The answer is yes. Hierarchy is not the proper term though, variables declared with "my" can only be "seen" by the rest of the script within the scope they are defined in. In your case the scope is the block, the stuff between {}.

Scope is the term.
