d data, use of paper tape

enabled batch processing.

The first units had five data hole positions plus a sprocket hole (for the driving wheel) across the width of the tape. These used commercial telegraph code (ITA2 also known as Murray), Baudot code or proprietary codes such as Elliott which were more programmer-friendly. Later systems had eight data holes and used ASCII coding.
