Some simple BASIC programs I’ve written.
Draw a tree
10 FOR I=1 TO 10
20 FOR J=1 TO 10-I
30 PRINT " ";
40 NEXT J
50 FOR K=1 TO I*2
60 PRINT "*";
70 NEXT K
80 PRINT
90 NEXT I
100 PRINT TAB(10) "**"
110 PRINT TAB(10) "**"Guess a number
10 RANDOMIZE
20 RAND=INT(10 * RND(1)) + 1
30 PRINT "I am thinking of a number between 1 and 10. Can you guess it?"
40 INPUT GUESS
50 IF GUESS <> RAND GOTO 80
60 PRINT "You're correct!"
70 END
80 PRINT "Sorry, the number was " RAND
90 END
