No problem.  "$#" returns the number of arguments passed to the script.
It does NOT count $0 (the script name itself).  Also "$?" returns the
return code from the LAST program run.  Generally, successful programs
return 0 and failures return non-zero, so:

	RC=$?	# Remember $? only works for the LAST program/script
	if [ $RC -ne 0 ]; then
	    echo Program failed, return code $RC
	else
	    echo Program succeeded\!
	fi

is a way to see if it was successful or not.  I assigned the value of $?
to RC because $? would be reset by the "if" statement itself.

ncftpget can be had from http://www.ncftp.com/download/.  There are
even precompiled binaries for AIX 4.3.3 on the RS/6000:

http://www.ncftp.com/ncftp/binaries/ncftp-3.1.8-aix4.3.3-export.tar.gz

I'd get the client for sure...it's a HUGE part of my toolkit.
