Application Version.

the SETTINGS->GENERAL SETTINGS->VERSION INFO->FIRMWARE VERSION
screen

selecting Save As from the File pull-down menu.

any logic elements that have a red X through them; they are invalid elements for the

and moving it slightly. BESTCOMSPlus will sense that the logic has changed.

toolbar.

be changed from the name given to it when it was saved after the Application Version
was changed.

“Before” the application version change to the version “After” the Application Version
change.

Files from the Tools pull-down menu.
