To transmit data that requires 2 or more lines of space at the terminal as one data-item, type an SBCS hyphen as the last character in each line except the last line. For example, to transmit the sentence “this data must be transmitted as one unit.” you enter:
:'this data must be transmitted - +:as one unit.'
Transmission does not occur until you press ENTER after “unit.'”. The hyphen is removed. The item transmitted is called a “logical line.”
