RE: Sending file data using TCP/IP

FTP is a great tool with a few limitations.  One of its strengths is
that it's file agnostic.  On the iSeries the ftp client has great help
text.  On the command line you can enter help cmdname and find out what
the command does or just enter help and get the complete help file. I
learned almost everything I know about ftp from the help.

The following assumes you're transferring files from one iSeries to
another:

First, packed fields in database files don't work well in FTP.  If the
file contains packed fields you need to work around it.  I think the
easiest way would be to use cpytoimpf to a delimited file in the ifs and
send the file you've created.  The receiver will need to convert it to
the required format. 

The receiver of the file has to know the file layout and supply you the
name of the destination file if you want to do a direct transfer.  If
you're sending a text file it doesn't matter. It's going to be a text
file on the other end.


If you're transferring files from an iSeries to different type of
system:

Database files all have a proprietary underlying format.  Unless the
sending system and the receiving system use the same database file
format **conversion is necessary**.  Text files are a lot more
forgiving. All you need to pay attention to is the end of line
character. Under certain circumstances you'll need to do a binary
transfer.  Usually it's not necessary for data.
