A boolean statement is either true or false. Here is a simple example of a Boolean statement. The statement B=(Z=7) will return a 1 for the value of B if Z is equal to 7, and will return a 0 for the value of B if Z is· not eq ual to 7. Add several of these together as in line 130 and you have a powerful statement. Suggestions: 1. Add random colors to the drawing by adding this line. 85 IF STRIG(0)=0 THEN COLOR INT(RND(0)*4) Press the trigger (red) button to change colors. 2. Can you make this program work in GRAPHICS 7?

Lines 130 to 180 change the cursor position.

Change the 32 in line 20240 to O. 20240 12=57344+«ASC(CHARS(U,U»-0) *8) Rewrite the program to display putting lower-case letters in from the keyboard. This change will get characters from a different part of the memory holding the character set. 2. Try it in another graphics mode. 110 GRAPHICS 6 :SETCOLOR 2,4,2 39 3. Try this program in GRAPHICS 4. Only ten bytes of RAM per line are required for this mode. 4.
