A word processing system is provided with separate data structures in system memory (4). One of these, the internal image, contains the calculated graphics image and another the operator\s alphanumeric character input. When displaying, the two images are merged together with the annotation overlay effectively overlaying the graphics overlay. In this way, if the operator erases something on the annotation overlay, the contents of the graphics overlay reappear. During the display of the calculated image and as the operator adds annotations to the display, overlaying conflicts between the graphics image and an alphanumeric character added by the operator are resolved in favor of the alphanumeric character. When an overlaying conflict does exist, the alphanumeric character is highlighted by video reversing to indicate that it is hiding a portion of the graphics image.

A word processing system having an interactive display terminal for displaying alphanumeric and calculated graphic images while maintaining the integrity of the calculated graphic data comprising: first storage means for storing data representative of calculated graphic data; second storage means for storing alphanumeric character data entered by a user; merging means connected to said first and second storage means for merging the data in said first and second storage means for display on said display terminal; detecting means in said merging means for detecting overlaying conflicts between the merged data by resolving said overlaying conflicts in favor of the data from said second storage means while preserving the data in said first storage means, whereby erasure of conflicting data in said second storage means results in the display of data from said first storage means previously in overlaying conflict with data erased from said second storage means, said detecting means providing an output indicating an overlaying conflict between the data in said first and second storage means; and means responsive to said detecting means output for causing the corresponding data from said second storage means to be highlighted in its display on said display terminal.
