  • Example: ** Maze - It can be difficult to work with text substitutions in Inform, because it often refuses to allow temporary values to be restored for later usage. Inline Hyperlinks uses text capture, however, letting us avoid such problems. This example shows how we can build links as needed to automate exit-listing. All hyperlink handling occurs in the "to say exits" phrase.

        The printed name of a room is "Maze". The description of a room is usually "A maze of twisty little passages, all alike. Exits: [exits]".

        To say exits:
            let count be the number of adjacent rooms;
            if count is greater than 0:
                repeat with destination running through adjacent rooms:
                    let the way be the best route from the location to the destination, using even locked doors;
                    let dir be indexed text;
                    let dir be "[way]";
                    let dir be "[dir]";
                    say "[link][way][as]go [dir][end link]";
                    let count be count minus 1;
                    if count > 0:
                        say ", ";
                say ". ";
