EBCDIC、ASCII与EBCDIC的关系及相互转化
2024-05-09 00:14:47
EBCDIC (Extended Binary Coded Decimal Interchange Code) 为国际商用机器公司(IBM)于1963年-64年间推出的字符编码表，根据早期打孔机式的二进化十进数(BCD, Binary Coded Decimal)排列而成。
EBCDIC编码中，英文字母不是连续地排列，中间出现多次断续，为撰写程序的人带来了一些困难。
ASCII比EBCDIC后出现，ASCII的编码方式参照了EBCDIC，将英文连了起来，方便了程序员记忆。因此，就连IBM的个人计算机和工作站操作系统也不使用它们所有的EBCDIC编码。相反的，它们使用文本的工业标准编码，ASCII码。
转化程序允许不同的操作系统从一种编码到另一种编码的转化。
（1）下面是ASCII和EBCDIC的编码转化表。
The following table shows ASCII and EBCDIC character code values along with their decimal,octal, and hexadecimal equivalents.
