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。

For your program to be able to read a record from the VSAM KSDS, the dataset must be in opened state in the CICS region.

您的程序将从VSAMKSDS中读取记录，数据集在CICS区域中必须处于打开状态。

Optimistic Locking is a strategy where you read a record, take note of a version number and check that the version hasn't changed before you write the record back.

乐观锁是这样一种策略，你可以读取记录，记录版本号并检查，在你写回之前该版本没有改变。
