Re: keyfield

Murali -

You will need to create a dummy indexed file that is keyed the way that your
OPNQRYF creates the keyed file, and compile your program against this dummy
file (with a K in the F-Spec), in order to use the random operations like
SETLL, CHAIN, etc.  This will also require that you perform a override on
this file name to the file opened by OPNQRYF.

By doing this, the RPG compiler will include the necessary code that allows
these operation codes to be used.
