Hi,

First of all you will create a directory called TEST, after that you will create a package called ( for example ) external_file.pm and inside of this package you will define your subroutine. To access this package in your code :

BEGIN {
    use TEST::external_file  ;
}
[download]

if you have any problem to create a package, look this site : (link to site containing copyrighted material removed)
