The delayifnotenhancedtn parameter of the <HAScript> element, when set to a non-zero value, causes the macro runtime to automatically pause the specified number of milliseconds whenever the macro runtime receives a notification that the OIA (Operator Information Area) has changed.

You can use this attribute if you developed a macro in a contention-resolution environment (you did not need to insert Pause actions) but you now want the macro to run also in a non-contention-resolution environment (some macro screens might need a Pause action to allow time for the application screen to be completed).

With this attribute set to true, then when the macro is run in a non-contention-resolution environment the macro runtime inserts a pause for the specified number of milliseconds each time it receives a notification that the OIA has changed. For example, if you specify a pause of 200 milliseconds then the macro runtime waits for 200 milliseconds every time the OIA changes.

The cumlative effect of the macro runtime pausing briefly after each notification of a change to the OIA is that the application screen is completed before the macro runtime begins processing the actions of the new macro screen. The macro runtime inserts these extra pauses only when it detects that the session is running in a non-contention-resolution environment.

A limitation of this attribute is that the macro runtime adds these extra pauses during every screen, not just during screens in which screen update is a problem. However, the additional time spent waiting is small. And more importantly, this attribute lets you quickly adapt the macro to a non-contention resolution environment, without having to test individual screens and insert a pause action in each screen with a screen update problem.
