That's one way of doing it. > function myRandom lower,upper > return trunc((random(30000)-1)/30000 * (upper - lower)) + lower > -- returns a whole number R, lower <= R < upper > end myRandom The way this function is written, myRandom(5,10) will only ever return values 5, 6, 7, 8, or 9, but never 10. So, if you want to occassionally return the upper limit, you can either call myRandom(glower, gupper + 1), or you can modify the algorithm so that it doesn't subtract one from the random value. That is, it uses: trunc(random(30000)/30000 * (upper - lower)) + lower Note if you call the function with a lower limit GREATER than the upper limit (eg myRandom(25,1)) the results might not be what you expect. -- Steven D'Aprano ========================================== M.B.
