Re: Reading records by key using C runtime record i/o functions

[Dennis <iseries@xxxxxxxxxxxx>]

Oops, you are right!  Not sure of those were added or if I've been doing it incorrectly/(the hard way) all this time.  Hmmm... I think I'd still stick with _rreadn() though since you are doing partial key.  Meaning, if you're looking for names that start with SM for example, seems to me that _rreadn() is the correct answer.
