Double height

The character is 20 pixels high

Double width

The character is 20 pixels wide. Available in Parallel

mode or in Line mode. Characters are stretched hor-

izontally, to occupy in addition, the next character

space. It is possible to mix it with double height. To

display a double width character the attribute must be

“double width” on the character and “simple width” on

the next which can be a serial attribute. In this case

the first character is memorised. If two “double width”

attributes are on two adjacent characters, the first half

of the second is displayed instead of the second half

of the first one.

Upper half character (if 1)

Active only if Double Height or Size requested
