Think of all the things you could do if you could put a special control character channel code in front of each line of data! Or a code character "0" that means "add a blank line". Or a code character "1" that means "go to a new page".

Or a code character that could act as a flag to "trigger a switch to a specific subroutine in the print formatting program before processing the next line of data". You can use these codes to enhance your control of font selection; data field selection and placement; conditional logic; variations in the number of lines of data on each page; and so on.
