Conditional job control

Conditional job control (CJC) uses job variables and the changes in their values for eventdriven job control. The user can refer to the contents of job variables in conditional commands. If changes are made to a given job variable (an event occurs), the system notifies all the jobs in which this JV is used in conditional commands. Even replacing a value by the same value counts as a change. If the specified condition is satisfied by the occurrence of an event, the desired CJC function is executed.

A complex control structure for job chains and job networks can be implemented with the aid of the functions described below.
