I have not had a chance to recompile the program on my Linux but but I did find some pointer bugs. I've added code to check for null values before processing a value and redid some of the login to make it smoother. As a separate note; I setup the environment used by the program on the Sun system based on the Linux system so all the environment variables were defined when I ran the program. I also made sure that tere were dummy data files. Thanks to everyone who answered my email. I know this was not the right place to post the question but I was not getting any responses in the C language groups I posted to. -- To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject.
