What is the difference between binary and Ascii systems?
Binary systems store up to 16 multiple replies (one or many replies occupy the same space) or one value per word. You do not need a data map because the data is always in the same place, whereas Ascii needs variable length fields and data maps. Binary occupies one eighth the disk space and is accessed eight times faster and processed as 16-bit parallel; this is 128 times faster overall. IBM SAP and Quantum are also binary systems in some respects, but are processed in a different manner. OMR reading is essentially a binary data process and is an excellent system match. Since binary fields are fixed-length, all the data replies for a complete record can be shown on one screen as position columns of reply values for data entry and validation.
