参考にしたソースコードをただコピー＆ペーストしただけではエラーが出たので、少し修正しました。

ソースコードの使い方

:以降の文字の所（出発点など）を自分の最寄り駅や行きたいところ、時間を変えるとその時間で表示されるようになります。

実行結果

11/9　17:00出発の横浜駅から番田駅の実行結果です。
左の写真の（変更はd）というところのように（変更はd）が表示された後にでdを押せば実行後でも場所や時間などを変更することが可能です。
右の写真は表示された乗り換え案内で、一番左のN1やN2はナビタイムで検索した、プラン1やプラン2ということになります。今回はNでしたが、Y（ヤフー）などで表示されることもあります。

まとめ

今回は乗り換え案内のソースコードを探してそれをコピーしたものをベースに修正をして作りましたが、そのままコピーしてペーストしてもエラーが起こることがわかりました。
また、もともとソースコードを作った人はこんなに長いソースコードを作成するのは大変じゃないのかなと感じました。
最後に、今回は乗り換え案内で作成しましたが、調べている段階でビンゴや時計などのソースコードも見つけたのでやってみようかなと思いました。
