Re: CCSID Changes during ftp_get

[Scott Klement <sk@xxxxxxxxxxxxxxxx>]

Hi Duane,

Yes, it would be nice if FTPAPI could set the CCSID of the local file to 
the same CCSID as the file it's downloading.  That would be awesome! 
Unfortunately, FTPAPI has no way to find out what that CCSID should be. 
  The FTP protocol does not have a mechanism to report the CCSID of the 
remote file, therefore FTPAPI has no way to know what that CCSID is, and 
consequently it can't set it to the same CCSID on the local side.

Please understand that CCSID is an IBM-only concept.  It's not used 
outside of IBM systems.  FTP was not designed purely for OS/400, it was 
designed as a general purpose tool for all systems.  And since the other 
(inferior, IMHO) operating systems have no notion of CCSID, it's not 
part of the FTP protocol.

Your best bet is to set the CCSID after the download.  The CHGATR CL 
command can do this.
     CHGATR OBJ('/path/to/myfile.txt') ATR(*CCSID) VALUE(37)

Alternately, pre-create the local file with the correct CCSID, if you do 
that, FTPAPI should keep the CCSID you specified.

Also... this isn't really related to the problem, but FWIW...  1252 is 
Windows Latin-1 ASCII, it's not Unicode.
