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+ PREPARE #SEL FROM :#SELCT2
C/END-EXEC
C/EXEC SQL
+ Declare CTLCURS SCROLL Cursor For #SEL
C/END-EXEC
*OPEN THE CURSOR
C/EXEC SQL
+ Open CTLCURS
C/END-EXEC
* if already opened close the cursor then reopen
C IF SQLCOD = -00000502
C EXSR $CLOSECURS
*OPEN THE CURSOR
C/EXEC SQL
+ Open CTLCURS
C/END-EXEC
C ENDIF

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.
