Dear Pandu,

one very simple procedure:

• Make lots with the numbers of your volunteers on it
  
• Take a hat and put the lots into it
  
• Mix them substantial (very important!)
  
• Now draw 20% of the lots (or better leave this job to a nice looking young woman)

and voilà - you have the numbers of subjects to report.

No terrible software like "The power to know" needed, no criticism of bad 'pseudo' random number generators .

If you cannot avoid SAS I suggest you Gooooogle:
