WindX & Javx
Turbo mode  
   
Overview During normal operation, each tokenized message sent by the host to the client requires an acknowledgment. While this process guarantees that the application and client are synchronized fully, it can slow down overall transmission speeds. However both JavX and WindX also support a 'Turbo Mode' which allows them to receive and process many requests locally without the need to acknowledge each transmission from the Host.

As can be seen in the above graphic, in the Normal Mode of operation, each packet sent to WindX/JavX receives an acknowledgment back confirming that it was executed and no errors were detected. When Turbo Mode is enabled, packets that don't return any information other than just an acknowledgement that they succeeded can be sent without waiting for a response from the WindX or JavX client.. Basically, while in Turbo mode, acknowledgments are not sent by WindX for directives and functions that do not return a value, for example, a write command for a graphical control.

If an error does occur during the execution of any of the commands received by WindX/JavX, it is reported locally or, in the case of WindX, can be ignored depending on the configuration option.

To enable Turbo mode, set the system parameter 'TU' on the host system. This is done automiatically be the NOMADS graphical environment
* Note * While Turbo mode improves performance, any code that relies on error detection may not work as expected. For example, relying on an error branch to detect a bad value when issuing a WRITE command to a control will not work. Either change the application logic or turn off the 'TU' system parameter to avoid this situation.

For Example:

LIST_BOX WRITE 10,"AAA",ERR=BADID

The above logic will not work in Turbo mode as the LIST_BOX WRITE directive returns no data thus the error will be reported locally.
