logic to prepare and close sql cursor

I keep getting this msg in the job log. This process is not halting, but 
something seems wrong. 
Below is a clip of the rpgle code that handles prepare, open, fetch, close. 
I do see that often when a select is run, and no records exist matching the 
select, it reaches the 
close section with sqlcod=100 and sqlstt=02000. 
I am assuming with these codes, the cursor is not open, and does not need to be 
closed.
Sorry for the length of this post, but I've searched many prev posts and cannot 
see exactly how 
this should work.
