BASIC Version 3.5 Commands, Functions, and System Variables 6?
2 multicolor mode extra color 1
3 multicolor mode extra color 2
4 screen border color
The color source number you include in the PAINT command tells the
computer to draw in the current color for that source. For example, if you select
1, the computer paints in the current foreground color. If you want to use a color
other than one of the current source values, you must first use the COLOR
command to change one of the source values. Only sources 1 and 2 can be used to
draw with more than one color on the same screen. Sources 0 and 3 are global
(whole screen) colors.
If you want to use the default value (1, the current foreground color), you do
not have to type a number, but you must type a comma before the next parameter.
2. The coordinates tell the computer wfyere to start painting. You can tell the
computer to start at any point within the space you want to paint. You never need
to include ending coordinates. The computer stops painting when the border is
reached.
3. Boundary mode lets you choose whether to have the painting stop when it
reaches a border of the color source with which it is painting (select 0), or when it
reaches any nonbackground color (select 1). The default is 0. The other choice is
meaningful only in multicolor mode.
Note: If the specified starting point was previously colored with a boundary
color, no painting will be done.
Example: 10 GRAPHIC 3,1
20 CIRCLE, 80,50,30,50,,,,90
30 COLOR 3,12,4
40 PAINT 3, 80,50,1
Draws a diamond and fills it in with
the color in color source 3.
PEEK
PEEK (memory location)
Abbr. pE
Finds the contents of any RAM location. The location must be between 0 and
65535. PEEK and POKE are complements and can be used together to place and
look at memory contents. Examining ROM using PEEK is not easy. See Chapter
4 (Copying the Standard Character Set) for one method.
Example: POKE 3090,1
PRINT PEEK(3090)
1
Displays an A at screen location 3090.
Prints the value of memory location 3090.
