Dataports

This property can be set dynamically by using the IMPORT Function (Dataport). Using this function in combination with the FileName Property, you can create dynamics dataports. Dynamics dataports are those for which it can be determined at runtime whether data should be input or output, and the name of the external file to read from or write to can be set.

Import can only be set dynamically in the OnPreDataPort Trigger.

If Import is blank, a default request options form tab is created, allowing this property to be set at runtime.
