RE: FTP from an RPG program

[Scott Klement <klemscot@xxxxxxxxxxxx>]

Hi Aaron,

I've called FTP from an RPG program with QCMDEXC before, so for what it's
worth, it's possible :)

One idea would be the scope of your override.  Remember, when you call
QCMDEXC with an OVRDBF, it will scope the override to the same actgrp as
your RPG program.  That's well and good, but the FTP command is what needs
to use it, not the RPG program :)

so, if your RPG program is not compiled with DFTACTGRP(*YES), your code
won't work.   In fact, you'd probably have to change the OVRDBF to do a
OVRSCOPE(*JOB).   (Which I really don't like to use....)

The next idea is...  you aren't checking for the CALL to QCMDEXC to fail.
What if it fails, then what?   You really should be finding some way to
find out which error message has occurred, and report it somehow.
Otherwise, when something goes wrong, all you can do is trial-and-error,
since you don't know what happened :)

As Dan pointed out, you might also want to try putting quotes around the
IP address.

You also might find my FTPAPI service program helpful.  The difference
there is that you issue the FTP commands yourself, instead of writing a
script, and then calling IBM's command.   Sure, writing an FTP script is
very simple, easy to do, etc...   but it's only easy if the FTP works all
of the time, and we all know that's not going to happen :)   With FTPAPI,
you can determine if things worked or didn't work much easier, you can
handle errors much better, you can handle "conditional situations" much
better (for example, doing something differently when a file exists or
doesn't exist)

And FTPAPI is open-source and completely free of charge.   So, it may be
worth a look :)
