+ * - String Names changed from A$ to sA
+ * - Arrays changed from G(8,8) to g[9][9] so indexes can

+ *** **** STAR TREK **** ****
+ *** SIMULATION OF A MISSION OF THE STARSHIP ENTERPRISE,
+ *** AS SEEN ON THE STAR TREK TV SHOW.
+ *** ORIGINAL PROGRAM BY MIKE MAYFIELD, MODIFIED VERSION
+ *** PUBLISHED IN DEC'S "101 BASIC GAMES", BY DAVE AHL.
+ *** MODIFICATIONS TO THE LATTER (PLUS DEBUGGING) BY BOB
+ *** LEEDOM - APRIL & DECEMBER 1974,
+ *** WITH A LITTLE HELP FROM HIS FRIENDS . . .

+ *** WESTINGHOUSE DEFENSE & ELECTRONICS SYSTEMS CNTR.
+ *** BOX 746, M.S. 338
+ *** BALTIMORE, MD 21203
+ ***
+ *** CONVERTED TO MICROSOFT 8 K BASIC 3/16/78 BY JOHN BORDERS
+ *** LINE NUMBERS FROM VERSION STREK7 OF 1/12/75 PRESERVED AS
