In modern data processing it is often necessary to transfer character data to and from an all-points-addressable graphics mode from and to a single ASCII byte stream. In the all-points addressable graphics mode, a character is represented by a number of bits equal to the size of the character cell. The bits are grouped in bytes. A typical graphics representation may consist of an 8 x 8 or 8 x 16 array of bits, forming 8 or 16 bytes per cell, respectively. To convert the graphics representation of the character into its equivalent ASCII code, it is necessary to compare the graphics representation to all character representations in the ASCII character set.
