//  abcde.iml   (c) 1998-2000 Kari Laitinen

//  This program prints the letters ABCDE to the screen.
//  Register A is used to count how many characters have
//  been printed. The character code being output to the
//  screen is held in register B. The first code is 'A'
//  which means 41H, the ASCII code of letter A.
//  As the ASCII code in register B is incremented after
//  each printing, a different letter will be printed
//  each time.
