 *	This program initializes the card files for monopoly.
 * It reads in a data file with Com. Chest cards, followed by
 * the Chance card.  The two are seperated by a line of "%-".
 * All other cards are seperated by lines of "%%".  In the front
 * of the file is the data for the decks in the same order.
 * This includes the seek pointer for the start of each card.
 * All cards start with their execution code, followed by the
 * string to print, terminated with a null byte.
