You don't really need to stop the user from sending an EOF, you just need to keep prompting for input until you get what you want:
until ($condition) { # Keep reading from STDIN. # Store and/or process the input. }

[Lady_Aleena]: Taking the printing functionality out of a module is hard at times. The one I'm currently working on has conditionals and loops for the data to be printed.
[Lady_Aleena]: Some are as easy as returning instead of printing, but only some.
[atcroft]: Lady_Aleena: So you are shoving the disparate data into a structure and returning the structure, so you can run it through a (probably simpler) routine that displays only?
