If there is already a variable with that name in that scope, it does nothing: no errors and no overwrites.</comment><header></header><code></code><translations>pt:cria as variáveis _ _

Each name will make only one variable deletion, and this will be the variable found following the scope order: 'script' ->'sprite' ->'global'.

If we have a "testing" sprite variable and also a "testing" global one, deleting "testing" will delete only the sprite one (Yes! we can also do "delete var (testing, testing)" to delete both.

If one variable does not exists (in any scope) an error happens, stopping block action in that point. You can check it before with the "does var (name) exists?"block. </comment><header></header><code></code><translations>pt:remove as variáveis _
