PARENTHESES KEYS
Numbers 8 and 9 on your computer keyboard
also give you the standard parentheses signs
when you press these keys at the same time
as a SHIFT key. In sentences, the parentheses
are used as regular punctuation (to set off a
phrase that further explains something). When
used in a BASIC command, they enclose num
bers or letters that have a predetermined
value. For instance, type in the following line:
PRINT CHRS| 14)
The number 14 stands for a specific keyboard
character (which changes the case this time).
SCREEN 1
Press the RETURN key now, and the letters on
the screen change from uppercase to lower
case—just as if you had pressed the SHIFT and
C= keys together to enter the Text Mode.
SCREEN 2
SCREEN 1
Use parentheses to enclose numbers or
letters that have predetermined values.
SCREEN 2
The value of this particular number (14) tells
the computer to enter the Text Mode.
To change back to the Graphics Mode now,
simply press SHIFT and C= together.
SCREEN 3
Do not clear the screen and do not turn off
the computer before going on to the next
exercise.
PR I N T CHR I ■ 1 -J
tEADV .
SCREEN 3
Using the SHIFT and C= keys together
returns the computer to the Graphics Mode.
