I’m not a statistician and can’t really help you on this, so am copying this reply to the list where you will get better advice. However, you need to give much more detail. Also, have you thought about the SRMS section of the ASA?

I need some guidance on what type of syntax I need in order to do the following:
In my study there will be 400 subjects, 200 in a control group and 200 in a treatment group (people who will receive specialized job training).
My colleagues have recruited people who fall into three categories (1) recently unemployed six months or less, (2) unemployed for 12 months and (3) unemployed for greater than 12 months.
Members of my group are interested in having different proportions of the people who fall into the aforementioned categories represented in the treatment group. For example, 20 percent should come from the recently
unemployed or 30 percent from the unemployed for greater than 12 months category etc.
Can you give me some advice on how to do this via syntax?
