These are just normal RPG subprocedures, you can pass variables to them.
Nothing fancy or exciting. :)

What happens when it doesn't work?  What error message does FTP_ERROR
return?

Brackets?  No.   This works for me:

DName+++++++++++ETDsFrom+++To/L+++IDc.Keywords+++++++++++++++++++++++++
D Site            S             30A   INZ('ftp.netscape.com')
D User            S             15A   INZ('anonymous')
D Pass            S             15A   INZ('me@xxxxxxxx')
D Filename        S             64A   INZ('/path/to/whatever')

C                   eval      sess = ftp_conn(Site: User: Pass)

...etc...

C                   if        ftp_put(sess: Filename) < 0
...etc...

I'm not familiar with things like "Datafile.file".   Are you running
Java?  Or V5R1?  This doesn't look like an RPG variable name to me...

Not without changing the code...  you could change the DiagMsg routine in
FTPAPIR4 to write the messages wherever you like.  There are a few points
regarding this that I'd like to make, however....

1) If you're writing to a file, and two jobs are running FTPAPI at the
     same time (or even if your job is running two transfers at once)
     the messages in the file will all get mixed together.    

     There are many ways to work around this, of course, such as keying
     the file by job & socket number, and putting those in different
     fields...   or putting the file in QTEMP...   or having a different
     file for each user.

2) You'd need some way to dynamically specify the file and library name,
     if you want this product to be able to work for other people in 
     other shops.

3) It might be wise to put '*****' or something in place of the password
     in the file, rather than putting the password where everyone can
     read it.

4) Another idea would be to structure logging the same way that I've
     structured the FTP_PUTRAW & FTP_GETRAW calls.  (i.e. the user can
      pass a procedure pointer, and have the FTPAPI call that procedure
      to do logging.)  This would allow greater flexibility.

4) If you come up with some good ideas or good code to do this, please
     send them to me or to the list, so we can all try them, and maybe
     integrate them back into the next release of FTPAPI.   Open Source
     software only works if people are willing to contribute :)
