My Massive Packet

[Ralph]

I'm sure most, if not all, professional programmers do care a lot about making their programs as user-friendly and bug- and fool-proof as they can.  But, most of us amateur programmers, like me, who can write code good enough to work if all the data is correct, usually don't go back and think of all the ways a program can fail, and add the additional code to take care of that sort of thing, as well as protecting the user against problems of all sorts, such as wrong type of data, proper user prompting, and so on.  I'm also sure that, atthe learning stage, as the OP obviously is, it should not be expected of him.
