A terminal used by an Account Executive to perform securities market queries and transactions must display industry unique characters and many fractions. This article describes how those characters can be implemented to conserve ASCII codes and to produce a very legible display of fractions. Fig. 1 shows the special industry characters. They are produced by combining a capital letter and a lower case letter in a single character display position. Each special character is assigned an ASCII code. Fig. 2 shows the fraction characters. Single-digit fractions, such as 1/8, 1/4, etc., are each assigned in ASCII code and are displayed in one character position. Double-digit fractions, such as 16ths and 32nds, are divided into two-character display positions.
