 What I'm really trying to avoid is a little different issue. I 
 process the statement:
  
           (SETQ ssnull (SSADD))
   
 and later,
   
           (SETQ ss1 (SSADD entnam ssnull))  
  
  If I recall correctly this is meant to reset a variable for a 
 selection set to nil ("ssnull"), because when the program is 
 restarted for the next run, I don't want to keep appending to the 
 same selection set, but start anew. But every time you issue 
 (SSADD), the system bumps up to a new selection set increment and 
 you get returned a prompt like "". Well, I don't 
 want to create a new selection set, but to just set the original to 
 nil and reuse the same one.
   
  I follow your response, I guess my original post (and probably this 
 one) was not that clear. Thanks for the reply...
