Should be simple.  The meaning of a subsetting if IF statement is that if the condition is NOT met then the data step loop stops. So 

if condition ;

is the same as 

if NOT condition then DELETE;

So in your case you want 

if name NOT in (&rvar) then delete;

Ah! The real problem is being a newbie in SAS. I just could have used:

if name in (&rvar) then delete;  

@Tom Thanks for your edit and answer Tom.
