Design a markup language for a train schedule such that printing, CRT display, retrieval, and CAI would be facilitated. Code enough of the Amtrak schedule to demonstrate how you would handle schedule problems and write symbol-action tables (10-12 lines each) for display and CAI. Define separately the complete set of symbols you use and their functions.

Note: You can ignore all material below the last line of the arrival/departure listing (i.e., below Newport News, VA).
