Star Micronics XB24-15, XB24-10 user manual by the parameter al, follows

The vertical definition of the characters is 16 dots in superscript/subscript modes, and 24 in all others. Each byte therefore represents half of the vertical definition of a character column in superscript/subscript mode, and a third of the vertical definition in other modes. If cn> bytes are required for a normal character, the arrangement of these bytes is as follows (where the byte numbers are represented by decimal numbers, starting at 0), and the total width of the character has been defined

by the parameter <al>:	Bit
	number
	1st
	Byte

2nd Byte

3rd We

In the case of a superscript/subscript character, the width has also been defmed by cur>, but only two bytes are required per vertical column, so the arrangement is as

follows:	Bit
	number
	1st
	Byte

2nd Byte
