Re: Re[2]: Fw: File in CL Program -- RPG400-L

Hi Jodi,

You are correct except that RCVF is available on *all* AS/400's, whereas the
READ, UPDATE, WRITE commands are only available where someone has installed
them. As a programmer going in cold to an AS/400 shop, I know RCVF will be
there, but even if READ, UPDATE and WRITE are there, how do I know they are
the same as the homegrown READ, UPDATE and WRITE I used at the last shop I
was in?
