Re: What record return from getNewRecord() ??

[francess@xxxxxxxxxx]

The RecordFormat.getNewRecord() returns an empty record for the particular
record format.  The typical use for this method is to set the contents of
the fields for the record and then use it to write a record to a file
(AS400File.write()).

The RecordFormat class does not return a record from a file, use one of the
AS400File.read() methods (read(), readFirst(), readNext(), etc.), for that.

For more information, checkout

In the left hand frame, expand Access Classes and then select Record-Level
Access.
