hi Bert de Jong,
Basically references are like pointers in C (of course there are
subtle differences).
eg . In perl. | In C (int var , *ptr);
$variable = "hello world";| var = 12345;
$reference = \$variable | ptr = &var
$reference is a pointer to $variable.
To access "hello world"
1. $variable ( the way you are familiar );
2. $$reference (pointer notation for scalars);
I think this will give you a basic idea.
If you want to learn more on references.
you can see "perlreftut" manpage.
pradeep.
