Some few basic Perl questions

[Mystik gotan]

Hiya,

I got some basic Perl questions. Hope you don't mind answerring them?

1) What is the use of just putting $var; on 1 line? Example:
#!usr/bin/perl -wT

# some code
$var;

Does this technique rescopes the variable?
2) Why is exit() or 1; used on the LAST line. I understand it being on some line when you need to exit. Also, exit() won't be too hard. I think (and I think I am possibly right), it exits because there are still some operations during. But why 1; on the end of the line? Does it wait for a true value of the whole script?

Think I've kinda missed these usements on Perl ;-)

Thanks for your help, already.
