a fetch doesn't need a prepare because it is done during cursor declare/prepare/open
I can explain it to you, but i can not understand it for you.

The SQL statement EXECUTE IMMEDIATE causes an SQL statement to prepare and execute, dynamically, at run time. The EXECUTE IMMEDIATE statement must be placed in the PROCEDURE DIVISION.

Unless, of course, one is using PL/I, Rexx, C/370, Java, or some language other than COBOL.
