Vectors

A vector is a group of fields on an RF screen. Fields with the same name can exist in separate vectors without conflict. This table shows the five vector types.


Vector type	Description
DISPLAY	Fields in the DISPLAY vector are only displayed to the user on the screen or used to hold data.
SEND	Fields in the SEND vector are the source data when executing a procedure call. These fields can also be displayed to the screen.
RECEIVE	Fields in the RECEIVE vector hold the data returned from a procedure call. They cannot be displayed on the screen.
HEADER/FOOTER	Fields in the HEADER or FOOTER vectors are display-only fields placed into the Screens’ header or footer areas.
