On each line

script

//*** WHAT CAN BE DONE STARTS HERE ***
//Create a function to do something with each line
//This one displays a message containing the text of the line

//Create another function to do something with each line
//This one displays a message containing the character count of the line

//function on every line and then finally say we're done.
