GRAPHIC DEMO ON THE 1000
by Dick Wagner
This month our program a also comes from Dick Wagner. This program could be used as an attention getter, as it does have some action. The PLOT pixel looks like it is jumping up and down a flight of steps. Line 10 and 50 PRINT the name and delete the PLOT pixel. This is a simple way to get around using PRINT AT. Try changing lines 20 and 40 to N,0 and lines 70 and 80 to X,0. This shows that PLOT will wipe out characters when using the same space. Then change line 20 and 40 to N,10 to give different action again. Try the original program but change 70 and 80 to X,0. To keep from deleting the bottom name, change line 10 to N=2 TO 43.
Code: Select all
1 REM AND EASY METHOD TO MAKE AN ACTION ATTENTION GETTER. 2 REM SEE T1MEX USER MANUAL PAGE 65 ABOUT PLOT MOVES THE PRINT POSITION. DID YOU SKIP OVER THIS? 3 REM USE RUN TO START THE ACTION. 10 FOR N=1 TO 43 20 PLOT N,N 30 PRINT "LAURIE G." 40 UNPLOT N,N 50 NEXT N 60 FOR X=43 TO 1 STEP -1 70 PLOT X,X 80 UNPLOT X,X 90 NEXT X 100 GOTO 10 200 REM THE WORD PRINT-OUT STARTS AT PLOT 0+3 BECAUSE PLOT CHARACTER IS 1/2 OF PRINT CHARACTER WIDE. THIS EXERCISE DEMONSTRATES REM 2 300 REM LINES 60-90 PRINTS PLOT PIXELS IN REVERSE. LINE 100 KEEPS THE ACTION GOING. LAURIE G. LAURIE G. LAURIE G. LAURIE G. LAURIE G. LAURIE G. LAURIE G. LAURIE G.
