Question 1: should this be a package.pl or a modual.pm?
If you want to be able to source the file via the use ModuleName; then the file must end in '.pm'.
Question 2: so I need to require 'package.pl'; but use 'modual.pm';
The syntax is use ModuleName; with no quotes, and no '.pm' at the end.
I'm still a bit cloudy on the differences.. other than modual is a package but a package is not a modual.
A module is a file with a '.pm' extension. Modules usually define at least one package, sometimes more. A package is a namespace, a compartment to hold variables, functions, etc.
Question 3: I am using this. ReadWrite:WriteData($filename,@Data); In teh package am I to use $_[0] and $_[1]? or can I use $filename and @Data?
In your ReadWrite package's WriteData() function, you will get the arguments from @_. $_[0] will correspond to $filename, and everything from $_[1] to the end of @_ will correspond to the elements in @Data.
