Re: ftp_quote not working

[Scott Klement <sk@xxxxxxxxxxxxxxxx>]

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 :)
