Pseudo random variable set

I would like to produce same sets of pseudorandom numbers with variable attributes from one seed. Code is not needed, some kind of logical process would be enough. Thanks

Long version: I have a seed (number, numbers, string, whatever) from which I want generate sets of pseudorandom numbers for which I can set some attributes, like interval, count. Yes, it looks like hash, but how to get variable sets from it? Some sort of mapping, perhaps? Yes, all computer generated numbers are pseudorandom.

Example: Seed - something 1. run; 1. settings - 1, 7, 34, 3, 57, 9 2. run; 2. settings - 165, 276, 976 3. run; 1. settings - 1, 7, 34, 3, 57, 9 ...
