Defining Chain Steps
After creating a chain object, you define one or more chain steps. Each step can point to one of the following:
A Scheduler program object (program)
Another chain (a nested chain) (A)
An event schedule or inline event (E)
A chain is a named series of tasks that are linked together for a combined objective. Chains are the means by which you can implement dependency based scheduling (B), in which jobs are started depending on the outcomes of one or more previous jobs.
