Passing command line parameters 1

I am very new to programming, so please forgive this rudimentary question...I am writing a utility that I would like to be able to pass a command line parameter at startup. I am using the ActivePERL port for WIN32. I am envisioning something such as the following for the CLI:

>perl ./myutil.pl parameter

and in my app I want to be able to assign a variable to the parameter. Such as:

$cliparm = parameter

I have tried using <STDIN>, but it is waits for user input &amp; thus doesn't accomplish what I want to. I want this to be seamless to the user.

Any suggestions will be most appreciated!

Thanks,
Stuart
