Template:NoteTA 腳本錯誤：沒有「Lang」這個模塊。（Template:Langx，擴增二進式十進交換碼），為IBM於1963年－1964年間推出的字元編碼表，根據早期打孔機式的Template:Le即一種二進化十進數（BCD，Binary Coded Decimal）信息交換編碼改進而成。是IBM迷爾級以上電腦的標準碼。

它的缺點是：英文字母不是連續地排列，中間出現多次斷續，為撰寫程式的人帶來了一些困難。

字符對應[編輯]

EBCDIC編碼表，最初定義了（不計空白字符在內的）88個可打印字符，同時還定義了減去26個小寫字母後的62個可打印字符的子集[1]：

在處理ASCII可打印字符之時，將其[佔位¢，其]佔位!，其!佔位（表示邏輯或的）|，而其^佔位（表示邏輯非的）¬，並補充上所缺少的屬於ASCII的6個標點符號，成為（不計空白字符在內的）94個可打印字符的編碼表：

在後來代碼頁版本的EBCDIC中，定義了「不變子集」58個字符，即在62個可打印字符子集基礎上再去掉4個被佔用了字符，並且計空白字符而不計$在內，如下圖灰色底所示。然後於各版本的編碼表中，加入了其他字符，以符合各地使用者所需。

以下是其中兩個版本的EBCDIC編碼表：CP037（英語）及CP500（多語言#5）。CP037為ASCII的[、]和^重新指定了位置不再佔用EBCDIC的¢、!和¬，將其!認同為原來EBCDIC的!。CP500為被佔用的EBCDIC的¢、|和¬重新指定了位置，將EBCDIC的!認同為佔用了其位置的!。
