COBOLで彼女をつくりたかった

# いろいろ勉強不足でした、クソダサコードしか書けませんでした。
こんなウンコードをご覧頂いて恐縮です。
こちら[https://paiza.jp/poh/ando](https://paiza.jp/poh/ando)にてウンコードを投げてました。paiza様、楽しいゲームありがとうございます。
一応レアアイテム以外はコンプしましたが、正直人様に見せるには恥ずかしすぎるレベルです。
「それでも」と言う大先輩方、アドバイスよろしくお願いします…
※下記のコードでアイテム解禁確認済み(使用言語:COBOL)

### つり目
```COBOL
        IDENTIFICATION DIVISION.
        PROGRAM-ID. Slant-eyes.
        DATA DIVISION.
        WORKING-STORAGE SECTION.
            01 IN-NUM   PIC 9(2).
            01 UNION-X  PIC X(30) VALUE "AnnAnnAnnAnnAnnAnnAnnAnnAnnAnn".
        PROCEDURE DIVISION.
            ACCEPT IN-NUM FROM CONSOLE.
            COMPUTE IN-NUM = IN-NUM * 3.
            DISPLAY UNION-X (1 : IN-NUM).
        STOP-RUN.
```
今回の中で一番短く書けた。UNION-Xの中身を見るとコーディングした人間のあたまのよわさが伺えます。

###ショートヘア
```cobol
        IDENTIFICATION DIVISION.
        PROGRAM-ID. Short-hair.
        DATA DIVISION.
        WORKING-STORAGE SECTION.
            01 INPUT-NUM1       PIC 9(3).
            01 INPUT-NUM2       PIC 9(3).
            01 OUT1             PIC 9(1).
            01 OUT2             PIC 9(2).
            01 OUT3             PIC 9(3).
        PROCEDURE DIVISION.
            ACCEPT INPUT-NUM1 FROM CONSOLE.
            ACCEPT INPUT-NUM2 FROM CONSOLE.
            COMPUTE OUT3 = INPUT-NUM1 + INPUT-NUM2.
            IF OUT3 > 99 THEN
                DISPLAY OUT3
                STOP RUN
            END-IF.
            IF OUT3 > 9 THEN
                MOVE OUT3 TO OUT2
                DISPLAY OUT2
                STOP RUN
            END-IF.
            MOVE OUT3 TO OUT1.
            DISPLAY OUT1.
        STOP-RUN.
```
桁数の対策がこれしかないとは思えないのだが…

###ロングヘア
```cobol

        DATA DIVISION.

            01 CTP                  PIC 9(1) VALUE 1.
            01 CTY                  PIC 9(1) VALUE 0.
            01 CTN                  PIC 9(1) VALUE 0.
        PROCEDURE DIVISION.
            PERFORM UNTIL CTP = 6
                ACCEPT INPUT-CHAR(CTP) FROM CONSOLE
                IF INPUT-CHAR(CTP) = "yes" THEN
                    ADD 1 TO CTY
                ELSE
                    ADD 1 TO CTN
                END-IF
                ADD 1 TO CTP
            END-PERFORM.
            IF CTY > CTN THEN
                DISPLAY "yes"
            ELSE
                DISPLAY "no"
            END-IF.
        STOP-RUN.
```
ただの比較ですがもう少し短くできないものか…

STRING句でPOINTERを使いたい人生だった。多分UNSTRING句でオーバーフロー（？）してる。

ダサくてごめんなさい、冗長でごめんなさい。STRING句でうまくPOINTER使えませんでした許してください。

うまく桁数を減らして表示できないものか…

##まとめ
固定長しか扱えないと認識してコーディングしてました。
全体的に同じような変数に値を移動させているのはチェックケースの関係です。
例えば数値3桁の変数に2桁の数値を入れると右揃えになり空いた桁に0が挿入されます。（例：32→032）
このためチェックケースと出力が合わなくて蹴られます。
私はこれを回避するためにMOVEで有効桁分の変数に入れなおす作業をしています。なんとかスマートにできないものか…

見ての通りひどいコードです、応用もへったくれもありません、仕様変更を言われようものなら血涙を流しながら1から書き換えるレベルです。
なんとなく高校でCOBOLを習っていたので興味本位でやりましたがさすがにキツイです。
レアアイテム以外揃っても結局、ワンピースとショートボブ。
一応レアアイテムも挑戦してみますがこの程度のCOBOLの理解度でどこまでいけるものか…
進捗があったら更新します。
