PAPPYD,
You hold the line as you would on any other spinning (open faced) reel. Grasp the rod with your right hand on top, depending on the size of the reel you can put the reel stem (part that connects reel to rod) between you're ring finger and little finger or leave your right hand completely above the stem. It just depends on what is comfortable for you. Regardless, pick up the line with your first finger, flip the bail over and cast as normal. BE SURE to LOCK DOWN THE DRAG. This will prevent the drag from slipping during the power portion of the cast and keep you from cutting your finger. Also as Big Bro said, try to find somebody near you as this is much easier when you can see whats going on.
