EXECUTE IMMEDIATE in Pro*C

Question

I am trying to use Execute immediate as following.
strcpy (sqlstmt, "select id_tag, desc from notice where id = 2");
EXEC SQL EXECUTE IMMEDIATE :sqlStmt INTO :id_tag, :desc;
Pro*C is not letting me do INTO, while same thing works in PL/SQL fine.
Any Idea on how to do this, other option for me is declare a cursor and do a FETCH INTO.
Thanks in advance.

If you wanted it that way, this is one way to do it:
#include <stdio.h>
EXEC SQL INCLUDE SQLCA ;
EXEC SQL BEGIN DECLARE SECTION ;
     VARCHAR sqlstmt[1000] ;
     VARCHAR userid[100] ;
     int     cnt ;
EXEC SQL END DECLARE SECTION ;
int main(void)
     strcpy(userid.arr, "scott/tiger") ;
     userid.len = strlen(userid.arr) ;
     EXEC SQL CONNECT :userid ;
     strcpy (sqlstmt.arr, "select count(*) from emp where deptno = :deptno");
     sqlstmt.len = strlen(sqlstmt.arr) ;
     EXEC SQL EXECUTE
          BEGIN
               EXECUTE IMMEDIATE :sqlstmt INTO :cnt USING 10 ;
          END ;
     END-EXEC ;
     printf("Count=%d\n", cnt) ;
     EXEC SQL ROLLBACK WORK RELEASE ;
}And the output:
D:\>dynamic
Count=3
D:\>
