A special library for supporting Jawi fonts in BGI mode

This paper introduces a method of writing Jawi script in Borland graphic mode (BGI); something that is not handled effectively with modern computer systems. The encoding algorithm of this method works by spanning the keyboard keys sequentially from left to right and top to bottom and outputting a numerical value for each key on the keyboard so that each key on the keyboard has a numerical code value. Special drawing functions are designed to draw the different Jawi letters. A Set is used to store the value (shape) of each letter including the letters that fall in the beginning, middle, and end of words as the letters in Jawi change their appearance depending on their position in the word. All the sets and the procedures that correspond to the Jawi letters are stored in one library file. This writing method was tested and it achieved a good, easy, and relatively speedy typing.
