TIMER Function Programming Example The following program searches for the prime numbers from 3 to 10,000 using a variation of the Sieve of Eratosthenes. The TIMER function is used to time the program. '*** Programming example for the TIMER function ' DEFINT A-Z CONST UNMARK = 0, MARKIT = NOT UNMARK DIM Mark(10000) CLS 'Clear the screen Start! = TIMER Num = 0 FOR N = 3 TO 10000 STEP 2 IF NOT Mark(N) THEN 'PRINT N, 'To print the primes, remove the 'remark delimiter in front of the 'PRINT statement. Delta = 2*N FOR I = 3*N TO 10000 STEP Delta Mark(I) = MARKIT NEXT Num = Num + 1 END IF NEXT Finish! = TIMER PRINT PRINT "Program took";Finish! - Start!; PRINT "seconds to find the";Num;"primes" END Sample Output Program took .1601563 seconds to find the 1228 primes
