my $argument = $ARGV[0] || die "No parameters given.\n";

I have an argument that gives me the message "No parameters given" if I dont put an argument it gives me the message above but how can I get it to prompt me for an argument if not entered at command line so it doesnt exit out of program each time I forget to put an argument at the command line???

Example:
scriptname #I enter my scriptname without an argument.

#output I would like to have if I forget to put in a parameter at command line.
You did not enter a parmeter, please enter a parameter:
