RE: Brain cramp: reading an IFS file from program running on PC

Looking at the javadoc, IFSTextFileInputStream doesn't override any of the
methods of its parent IFSFileInputStream so I don't see how the "read"
methods invoked by Properties.load() can do anything other than what the
IFSFileInputStream does. Like any InputStream, IFSFileInputStream does no
charset conversion. All that IFSTextFileInputStream does over
IFSFileInputStream is add the read(length) method. The
DavidIFSTextFileInputStream overrides the "read" methods to use the
read(length) method to do what you want.

Oh, I think I see what you're talking about now. Properties.load()

native byte representation on the 400 since InputStreams don't take the

take that into account. Also, you'd need to make adjustments where the
CCSID was not a single byte character set.

This is what I assumed the IFSTextFileInputStream class would do. Reading
from a text file in Java should convert from EBCDIC to Unicode
automatically.

Otherwise it seems to be a waste of code.

I'm 95% sure it DOES do that ... but I just can't figure out what I'm

doing

wrong.
