PRED is used to draw single and double lines and also assign fifteen text colors on the help screens. Line drawing and screen colors are best added during a second phase with the first phase being the creation of unadorned menu and text screens. Before putting too much time in adornment, look at an unadorned file of help screens in action. Modifications will become apparent and are easiest on simple screens. After a shakedown period, PRED line drawing and text coloring can begin since the screens will be fairly stable.
Line drawing with PRED is more basic than linedrawing with some wordprocessing software.
PRED linedrawing operates awkwardly and does not automatically substitute tees and crosses at line intersections. Tees and crosses and other IBM graphics characters are available within PRED by pressing the ALT key and numeric keys. Polaris Rescue displays in monochrome or color and runs under DOS 2.0 or higher.
