RE: ftp_quote not working
Scott,
As always, you have explained perfectly what is happening. I used the array technique to get the job done while waiting for an answer.
I hate putting limitations on any programming method (array processing) but I don't think there will ever be 9,999 files on the server side for each type anyway. (audit and batch). The server side xml files may have up to 6 years of data with 2 or 3 files per day but should be purged after that year by year.
Thank you,
Craig

Subject: Re: ftp_quote not working
hi Craig,
In an FTP client, the "QUOTE" subcommand is used to send raw FTP protocol data from the client to the server.
When you log in "by hand" (as you put it) you are NOT using quote at all. You are simply typing the commands that you want to run into the client, and it is interpreting them and running them. So all is well.
You've told FTPAPI to send 'ls audit* (disk' to the FTP server as if it's FTP protocol data. It is not. The FTP protocol has no notion of an 'ls' command.
In the IBM FTP client for i. (Which is what you've termed doing it "by
hand") you type "ls audit* (disk", and that is NOT sent to the server as is. Instead, the FTP client reads it. It knows what "ls" means, so it sends the "NLST" FTP command. The (DISK part is not part of the FTP protocol at all, but rather is an instruction to the IBM FTP client (and is peculiar -- a feature that doesn't exist in any other FTP client I've ever heard of -- at least, not with that syntax.) Furthermore, because the client understood and interpreted your command, it sets up the data connection to transfer the directory listing for you. That's something else that would not happen if you sent the raw FTP protocol yourself.
To compare apples to apples, go into the IBM FTP client (i.e. "by hand") and try the following command:
QUOTE 'ls audit* (disk'
(That is, after all, exactly what you told FTPAPI to do.)
Anyway, FTPAPI is a programmatic interface. It doesn't know how to write a directory to disk. It has the option to return a directory listing straight to your program (in an array) or to use a callback subprocedure to send the file names one at a time. If you wanted it written to disk, you could easily write code to do that, since the RPG programming language has a rich array of options for writing data to disk :)
