A package is a namespace. All "global" variables (aka "symbol table" or "package" variables) and subs live in a package. The package statement is used to define the default package to be used if no package name is explicitly specified when the variable or sub is referenced. A module is a collection of routines and/or data, decleared in one (or possibly more than one) package and bundled into a source file for reuse and distribution. Certain Perl constructs assume a correspondence between package names and module names. The perlmod and perlmodlib documents go in to detail on these topics. perldoc perlmod perldoc perlmodlib perldoc -f package perldoc -f use -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
