Good news: What you seek is already available. In the following, all parameters are assumed to be integers.

RANDINT(n,a,b) --> n random integers between a and b inclusive, with possible duplicates.

rand(n,a,b) --> n random integers between a and b inclusive, with no duplicates. Of course, b-a must be big enough to accommodate n items, else an error occurs.

Notice that rand must be spelled in lowercase, whereas randint works in both uppercase and lowercase.

Alternative method: CAS.RANDOM(n,a,b) seems to be the same as rand(n,a,b), but CAS.RANDOM must be spelled all in uppercase.
