Concurrency Considerations

A user is given the version of the menu that is current when he first displays the menu, that is, a menu is not reloaded between the selection of options on the same menu. Therefore, if a menu that is being displayed at one workstation is changed at another workstation, the change does not alter the displayed version until the displayed version is refreshed. Refreshing will occur if a second menu is called, and then the original menu called again.
