Always prompt for input. Tell the user what you expect him to do. (e.g. Enter 6 numbers seperated by "Enter Key". Or Enter a list of numbers seperated by "Enter Key". Terminate with eof (ctrl-z)). This prevents most of the problems caused by the user not knowing that the program is waiting for him.

Even better, use a prompt module. In this case, it may be overkill, but it is worth learning how to use one.

[choroba]: sorry, that's high-end, of coursse
[choroba]: low end, in my talk, will be code that "we don't touch because it works" and noone knows why
[choroba]: I want to present the most bizzare bugs and misfeatures I met when working for a large financial institution
[choroba]: I already gave a similar talk to my friends in a pub and at an internal conference at work and people liked it, so maybe...
[choroba]: LanX: That's the heritage, I can't do anything else
[RonW]: Sounds like some system my employer has "It does exactly what we need it to do and can't afford to risk anything we can't prove is 100% compatible"
[marto]: choroba sounds interesting
[RonW]: james28909 Why not write a Perl program to do the task?
[choroba]: RonW Yes, but then, one day, they needed to switch from FTP to SFTP, and... but I can't give the whole talk away here :)
