Line 20 generates the numbers. Line 40 selects thetenth number from each set.Program Listing10 LET T=J15 LET V=J20 LET T=INT(lOOO*RND)30 LET V=V+l40 IF (V/lO)=INT(V/10) THEN PRINT V,T50 GOTO 2062 Random SamplerThis program strengthens your confidence in the ran•dom number generator built into your TIMEX computer.It generates 100 numbers between zero and 100 andtells you how many of those are above 49 and how manyare below 50. See the sample RUN for several sets ofresults in our recent test.Program Listing10 LET N=Jj15 LET X=J20 LET Y=J25 FOR L=l TO 10030 LET X=INT(lOO*RND)35 IF X49 THEN LET N=N+l45 NEXT L50 PRINTY;• YES"55 PRINT N;" NO"60 PRINT65 GOTO 1078

It prints a random numberfrom zero to nine every time. For your use here, we printthat number on the screen. You could just as easily havethe computer store that random number in a memorylocation for later recall and use.We have added lines 10, 30 and 40 to make yourTIMEX show you a whole series of random numbers fromzero to nine. Remember, line 20 is the important singlelineprogram element here.If you would like random numbers in the range fromzero to 99, make it 100* in line 20. For zero to 999, use1000* in line 20.Program Listing10 RAND20 PRINT INT (lO*RND)30 PAUSE 10040 GOTO 2079
