Goto accepts the use of variable value to act as the label to goto.
Example:
@echo off
echo a = 1
echo b = 2

goto %foo%
However, you should check the input so it will not go to somewhere that does not exist. Going to an undefined label will terminate...
Throwable has two direct subclasses, Exception and Error. While it's possible to create a new class that extends Throwable directly, this is inadvisable as many applications assume only Exception and Error exist.
More to the point there is no practical benefit to directly subclassing Throwable, as ...

var="hello"
function foo(){
echo $var
}
foo
Will obviously output "hello", but this works the other way around too:
function foo() {
var="hello"

Will also output "hello"
function foo() {
local var
var="hello"
}
foo
echo $var
Will output nothing, as var is a variable local to the function foo, and its value is not visible from outside of it.
