The next step is to write a sample COBOL CICS program to read a record from VSAM dataset based on a record key.
下一步是编写一个COBOLCICS程序，以便基于记录键(record key)从VSAM数据集中读取一个记录。
Most often this feature is ignored, and password text boxes simply record key-press events and ignore key-release events.
这项功能经常被忽略，并且密码文本框只记录按键事件而忽略释放事件。
This program accepts an operation code and a record key as inputs, then reads the VSAM dataset and returns the record back to CICS.
