The Math Character Set
When the Math Set is selected as the active alternate character set, the keyboard generates the
mathematical symbols shown in Figure B-1. You may construct the integral sign to occupy two,
or several, screen rows. Similarly, you may construct left and right brackets of varying sizes.
However,
drawing the top and bottom "corner" segments of these figures requires your access-
ing the Line-drawing character set. Some examples ofall three symbolsfollow. (For the bracket
symbols, "L:" signifies that you must activate the Line-drawing character set. The remaining
symbols correlate to 'the Math character set.)

Once the Math set has been selected as the Alternate Character set, you enable it with a < 5 a>
control code (control-N) and disable it with a <5 i > control code (control-O).

The Line Drawing Set
When the Line Drawing set is selected as the active alternate character set, you can construct
data entry forms by combining different types of line segments. Figure B-2 shows the cor-
respondence
between the line-drawing characters and the USASCII keyboard.
Once the Line-drawing set has been selected as the Alternate Character set, you enable it with
a <so> code (control-N) and disable it with a <5 i > control code (control-O).
