Your premise is false. Just because
the seed remains the same does not 
imply identical samples (of a given size). 
Conversely, explicitly setting the seed to the 
same number as before the last 
call does ensure an identical sample. 

However, you can indeed change the seed easily. 

. search seed 

points to ways of doing this. 

More generally, there is a great
deal of help on-line, which will 
save you time.
