The following text is from one of my stored manuals.

------------------
-519   THE PREPARE STATEMENT IDENTIFIES THE SELECT STATEMENT OF THE OPENED 
CURSOR cursor-name 

Explanation:  The application program has attempted to PREPARE 
(actually,re-PREPARE) the SELECT statement for the specified cursor at a time 
when that cursor was already open. 

System Action:  The statement cannot be executed.  The cursor was not 
affected. 

Programmer Response:  Correct the logic of the application program so that it 
does not attempt to re-PREPARE the SELECT statement for a cursor when that 
cursor is open.

OK, So i've gotten away from trying to retro fit a subfile program with SQL
and am writing it from scratch.  
The program lets the user hit a command key to select a sorting option.
after selecting the sort it goes and trys to prepare and close/open my
cursor.  The problem i'm having is i'm getting a -519 error on the prepare
the 2nd time it hits the statement.  

how should i handle this??

here is the sql code.


 C                   EVAL      #SELCT2 = %TRIMR(#SELCT1) + ' ' + #SORTFL 
 C/EXEC SQL

 C/EXEC SQL

 C/END-EXEC                                                              
                                                                         
  *OPEN THE CURSOR

 C                   EXSR      $CLOSECURS            
  *OPEN THE CURSOR                                   
 C/EXEC SQL

Using embedded sql for display file pgms is nice. It
reduces the lines of code, makes sorting on different
columns easy, and makes page up easy. 

There was an article in midrange computing about a
year ago that shows how to do it.  I think the
Sorcerer's Guide redbook also talks about.

What I do (there are probably other ways) is:
1. prepare a cursor (this is where the select is)
2. declare that cursor as scrollable
3. open that cursor
4. fetch from the cursor.  You can fetch next, prior,
first, current, or rrn.
