The initial program load (IPL) for a video display system normally contains a set of initial document format default values. Disclosed is a method of providing an operator with the capability of overriding the initial document and alternate format values on a page, line, or mid-line character basis by format change to suit the operator's requirements. A key concept is that these format changes are stored in the document as "fixed formats". That is, a format change records the values displayed on the format change menus for each formatting option whether or not the value was selected and changed by the operator. Therefore, the values stored will be either the value(s) selected and entered by the operator or a value shown on a menu when a key is pressed.
