For examples: 00000000 to 11111111 has 256 egg patterns for yes/no data of eight days; 00000 to 22222 (system of no egg, one egg and two eggs) has 35 patterns for egg production of five days; and 0000 to 3333 has 44 patterns for system of no egg, one egg, two eggs and abnormal eggs in four days…etc.

利用诸如 Fortran Compiler提供的 ACHAR 与 IACHAR 对应函数与自建的转换对照表，可以256 (=28)个ASCII字元储存各类变化的产蛋记录；如28 (00000000→11111111)：八天的&有生蛋、没生蛋&的资料或是35 (56)：五天的&没生蛋、一个蛋、两个蛋&的资料或是 44(0000→3333)：四天的&没生蛋、一个正常蛋、两个正常蛋、异常蛋&的资料EEE等。
