Advice on randomization

stace swayne
Dear List,
I need advice 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 anyone give me some advice on how to do this via syntax or suggest an online resource?
All suggestions are welcomed.

There's probably something here that will do what you want, or at least give you an example you can tweak.
