Embedded SQL question

Hello all,

I'm trying to use dynamic embedded SQL to retrieve a value in a program.
I was originally trying to use host variables for the needed data but then
I found out that you can't use host variables in dynamic SQL and that you
have to use parameter markers instead. So here's what I have:

MySQLText = 'Select rrn(a), a.' + %Trim(Field_Name) +
' Into ?,?' + ' From ' +
%Trim(Library_Name) + '/' + %Trim(File_Name) +
' a where rrn(a) = 1';

exec sql
SET OPTION
commit=*none,
datfmt=*iso;

exec sql prepare selectRecord from :MySQLText;
exec sql execute selectRecord using :rrn,:OldCompany;

When I run the program in debug, the MySQLText field looks like this:

Select rrn(a), a.CONO15 Into ?,? From COPYAULT2/INP15 a wher
e rrn(a) = 1

and I get the following errors:

Token ? was not valid. Valid tokens: : <IDENTIFIER>.
Prepared statement SELECTRECORD not found.


I'm stumped as to what to do from here. This SQL statement should yield
one record (and does when run interactively) and the thing I'm trying to
grab is the value in :OldCompany.

Any help would be MOST appreciated. Thanks!

Bill
