OPNQRYF Question

I've got a little logic problem when working with OPNQRYF that I 
know I can do in straight SQL (which is not available for my 
process).  I'm thinking OPNQRYF might not be able to handle it.  
Essentially I want to do the following via the OPNQRYF command:

SELECT * FROM COURSES
  WHERE SOMECODE = "" AND
  LOCATION IN 
    (SELECT ID FROM TABLELOOKUP
     WHERE LEVEL = "02" AND (TABLEID = &TNAME1
           OR TABLEID = &TNAME2)
    )

Basically the user could enter up to two region names (&TNAME1 
and &TNAME2) which use a lookup table containing the real location 
codes that have to be compared with the codes on file.

Can someone tell me whether this is possible or not?

Thanks.
