Formula Structure

Programming

Programming Sequence

Each Formula is entered into the reader by the following sequence:

Input_ID >> Length >> Match >> A-String >> O-String >>...>> O-String >> Enter

A Formula starts with Input_ID and ends with “Enter”(a label in programming sheet). If a field is

optional and missing, the next one in the sequence can be entered. But “Enter” must be the

last input of a formula.
