Now if I want to add an option to restart a game, I could just call the restart-game word again but as I understand it, this would grow the stack. Maybe I should restructure the code in this case to a control flow better suited for these new specifications instead. > > Obviously, if case a b or c *is* detected, then the default (i.e. no > match) code is *not* executed. Have a look at BEGIN...UNTIL. That > might be better for your needs. Here's an example: BEGIN...UNTIL look like a candidate for said restructuring. Thank you! Christian
