If you hold down the fr key while turning on
the computer, you can immediately access
C64 mode.
Function Keys
The four keys located above the numeric keypad (marked F1, F3, F5
and F7 on the top and F2, F4, F6 and F8 on the front) are called func
tion keys. In C128 and C64 modes, you can program the function
keys. (See the KEY command descriptions in Section 5 of Chapter II
and in Chapter V, BASIC 7.0 ENCYCLOPEDIA). These keys are also
often used by prepackaged software to allow you to perform a task
with a single keystroke.
Displaying Graphic Characters
To display the graphic symbol on the right front face of a key, hold
down the SHIFT key while you press the key that has the graphic
character you want to print. You can display the right side graphic
characters only when the keyboard is in the upper-case/graphics
character set (one normal character set usually available at power-
up).
To display the graphic character on the left front face of a key, hold
down the C* key while you press the key that has the graphic charac
ter you want. You can display the left graphic character while the
keyboard is in either character set.

Rules for Typing BASIC Language Programs
You can type and use BASIC language programs even without know
ing BASIC. You must type carefully, however, because a typing error
may cause the computer to reject your information. The following
guidelines will help minimize errors when typing or copying a pro
gram listing.
1.
Spacing between words usually is not critical; e.g., typing
FORT = 1TO10 is the same as typing FOR T = 1 T010. However,
a BASIC keyword itself must not be broken up by spaces. (See
the BASIC 7.0 Encyclopedia in Chapter V for a list of BASIC key
words).
2.
Any characters can be typed inside quotation marks. Some char
acters have special functions when placed inside quotation
marks. These functions are explained later in this Guide.
