Abstract

A method is described which removes the concept of page boundary limitations for an interactive text processing system while operating in cursor draw mode. In DisplayWrite 3*, a cursor draw function has been introduced during text edit. One of the features supported by cursor draw is the dynamic expansion of the cursor draw area at page boundaries. When the operator initiates cursor draw by pressing CTL+F5, the system posts the cursor draw command line. The options on this command line are as follows: Draw_with_cursor Erase_with_cursor Change_draw_character The first command is initially shown in reverse-video. The system initially defaults the draw character to be "lines." This enables the operator to draw lines during text edit. A good example would be to draw boxes around the text.

Dynamic Expansion of Cursor Draw Area at Page Boundaries

A method is described which removes the concept of page boundary limitations for an interactive text processing system while operating in cursor draw mode. In DisplayWrite 3*, a cursor draw function has been introduced during text edit. One of the features supported by cursor draw is the dynamic expansion of the cursor draw area at page boundaries. When the operator initiates cursor draw by pressing CTL+F5, the system posts the cursor draw command line. The options on this command line are as follows: Draw_with_cursor Erase_with_cursor Change_draw_character The first command is initially shown in reverse-video. The system initially defaults the draw character to be "lines." This enables the operator to draw lines during text edit. A good example would be to draw boxes around the text. If the operator then selects the "Draw_with_cursor" option, the system will initiate cursor draw using the active cursor draw character. While in this special keying mode, the following cursor motion keys perform the cursor draw function: cursor right/left and cursor up/down. The cursor draw area is not bound by page boundaries. For example, if the operator draws down to the end of the page, the system automatically creates an extra line and inserts the draw character on this new line. In an identical fashion, if the operator draws up to the top of the page, the system automatically creates an extra line and inserts the draw c...
