本文详细介绍了DataStage中用于作业控制的各种函数，包括启动、停止作业，获取作业信息及状态等功能。这些函数有助于实现复杂的作业流程管理和监控。

These functions can be used in a job control routine, which is defined as part of a job’s properties and allows other jobs to be run and controlled from the first job. Some of the functions can also be used for getting status information on the current job; these are useful in active stage expressions and before- and after-stage subroutines.[@more@]
