<li>When ONLINE(*YES) is used, specifying a wait time in the line description affects system IPL time. In such cases, system IPL time is influenced by the amount of time required to synchronously vary on the line or reach the wait-time value.
|

</li>
|

<li>The time required to vary on a line is the time it takes to:

<li>Put tasks in place to manage the line
|
||
|
|
</li>
