Loop in Nawk Script

I have a script which performs a getline (customer enters data) and a list is returned which has the data that was entered return to them. Then it ends. How can I get this script to return to the begin and ask the question again.

Ths script needs to stop after the list is returned and then hit enter to continue or quit to end.

The getline is in the BEGIN section.

Thank You
