If you find yourself using

 0→G ;or any other variable
 ;other lines of code

Then, you could use (to save a byte):

 DelVar G;other lines of code

This is because when you delete a variable (`G`), it becomes its default value, in this case, `0`. Then, you could put another line after the `DelVar ` statement, _without a newline_. Be careful when putting crucial control statements directly after a `DelVar ` statement.
