What you want is a perl module file. The basics are documented in the documentation of perlmod under "Modules" . Here is a trivial example: This script uses say_hello: `#! perl -w use strict; use warnings; use mystuff; mystuff::say_hello "world";` [download] ... and say_hello is defined in this script, which should be saved as "mystuff.pm" in the same directory. `#! perl -w use warnings; use strict; package mystuff; sub say_hello { print "hello " . shift() . "\n"; } 1` [download] If you run the first script above with `$ perl -w example.pl` [download] it will print `hello world` [download]	[reply] [d/l] [select]

Sure, put them in a seperate file and use, require or do. After Compline, Zaxo	[reply]

Hello. quester's example is great. But if you don't like the idea of having to write `mystuff::hello`, you can either omit the `package mystuff` line in the module, which may not be a best practice or you can `use`Exporter`; @EXPORT_OK=('hello');`	[reply] [d/l] [select]

You could have a look at this post in another thread for a small, real-world example of module use. Note that my module `use`s the `POSIX` module which is part of the standard Perl distribution. I hope this is of use. Cheers, JohnGG	[reply] [d/l] [select]
