Abstract
Abstract There is an area which we have hardly touched, that of the position of characters in a font. The characters in a font may be accessed in a number of ways. We are accustomed to the ‘normal’ way, by actually specifying the character - a, b, c, similarly,some characters are accessed through commands Since there are 128 characters in Computer Modern, it is convenient to divide the table into groups of eight or 16. There is a convenient way to refer to octal (base 8) or hexadecimal (base 16) numbers, rather than decimal numbers. For example, the following are equivalent: \char' 152 and \char"6A. An octal number is preceded by a ', while a hexadecimal number is preceded by a 11 Note that the hexadecimal numbers use the upper-case alphabetic characters. Using lower-case will lead to trouble.
