This example procedure is based on the AutoCAD Romans font file, although a similar
method applies to any font. This procedure adds four new shape definitions to a font:
super_on, super_off, sub_on, and sub_off, which control the position and size of the
characters that follow. For simplicity, this example replaces the brackets characters
([ and ]) and the braces characters ({ and }) with the new characters. You may choose to replace other characters or use a shape
number in the extended range (ASCII codes 128 through 256). If you use an extended
shape number, you need to use the %%nnn method for placing the new characters (where nnn is the ASCII value of the character).

1. Edit your SHP file with an ASCII text editor (for example, Notepad on Windows or TextEdit
   on Mac OS).
2. Search for the shape definitions of the characters you are replacing. To comment out
   those definitions so the new definitions can take their place, insert a semicolon
   in front of each line of the shape definition. The shape definition may continue for
   a number of lines.

   The left- and right-bracket characters have ASCII values of 91 and 93 (05B and 05D
   hex values, if the font is Unicode). The left and right curly brace characters have
   ASCII values of 123 and 125 (07B and 07D hex).

3. Add the first and second values on the second line of the definition, and divide the
   total by 2 as shown in the following example:

   *UNIFONT,6,Extended Simplex Roman for UNICODE
   21,7,2,0 21 + 7 = 28, then 28 / 2 = 14. This number is used later.

4. Add the following lines to the end of the SHP file:

   *91,8,super_on 
   2,8,(0,14),003,2,1,0 
   *93,8,super_off 
   2,004,2,8,(0,-14),1,0 
   *123,8,sub_on 
   2,8,(0,-14),003,2,1,0 
   *125,8,sub_off 
   2,004,2,8,(0,14),1,0

   Notice the 14 and -14 values in the preceding lines. They are Y axis offsets for the imaginary pen. The value 14 is half the maximum height of a
   character in this font, which is the correct approximation for superscripts and subscripts.
   This value needs to be calculated for each font file, but you can modify it any way
   you want.

5. Save the file.
6. Use the COMPILE command to compile the SHP file.

   Once the shape is compiled and an appropriate style is defined, you can access the
   new pen-up and pen-down commands by entering the brackets ([ and ]) and braces ({ and }) characters. The [ (left bracket) character initiates superscript and the ] (right
   bracket) character returns from superscript to normal. The { (left brace) character
   initiates subscript and the } (right brace) character returns from subscript to normal.
