15.1.8 Settings for using wait conditions

When you use wait conditions to control the execution order of units that are in different jobnets, you need to enable wait conditions.

Wait conditions are disabled by default. To use wait conditions, you need to set the PREWAITUSE environment setting parameter.

Use the PREWAITEXTEND environment setting parameter to extend the wait condition function.

The following describes the procedure for using wait conditions.
