I have a COBOL program that is called in a script that runs 
overnight via cron, on my Slackware system. It updates two 
html files which are then sent upstream to my two websites.   
Therefore the batch mode ftp update program (ncftpput ) 
must be able to read these two files. I don't know what 
user the ftp program runs as. So I just stuck two chmod 666 
statements into the script.  All the files are owned by my 
user name. I was getting error messages before I put in the 
chmod statements.
