RE: IFS file to PF Member

["Daniel Feather" <DFeather@xxxxxxxxxxxxx>]

Gary,
        That makes sense. Performance is actually the main issue. The
code I inherited is ftp'ing the IFS ASCII text file to the member.
Apparently, there is a conversion that takes place during the ftp
process automagically when using the FTPClient in jt400. Do you have any
idea whether or not the performance would be different (better OR worse)
if I used IFSTexFileOutputStream instead of ftp'ing the file from the
400 to itself? The ftp thing seems like a hack to me, and leaves a
potential hole open on the system and I'd like to get away from it if it
makes sense from a performance stand point. I am going to go ahead and
do my own comparisons, but since you see, to be more experienced with
this than I, maybe you have some more insight. Thanks for all your help!

Dan --

If your byte array is in ASCII (from an ASCII IFS file), then your
output
will also be encoded in ASCII, as you are seeing.

You need to convert that byte array to EBCDIC in order to write EBCDIC
using
IFSFileOutputStream.write(byte[]).  If it's just a string of text, you
might
want to use IFSTextFileOutputStream.write(new String(byte[])),
especially if
performance is not a big issue.  If the record structure is more
complicated, you probably want to use SequentialFile and record level
access.
