// List of variables needed in Storyline for this code to work correctly:
// 1. MESSAGE (input): A text variable that holds the message to be translated to Morse code.
// 2. MORSE (output): A text variable that stores the translated Morse code.
// 3. DOT_DASH (output): A text variable that indicates whether the current Morse code character is a dot, dash, or blank.
// 4. END (output): A true/false variable that indicates when the translation is complete.
