Creating a Field

There are two ways to identify a field: by a constant position on the page or a position relative to some constant string on the page. If the data is printed at the same position on the page every time, use a fixed field. If the data floats on the page but is always positioned relative to a constant string (text or hexadecimal), use a reference field.

For complex print streams, such as AFP and Metacode, you may want to display an explanation before you create a fixed or reference field. Visual Engineer can display a line-by-line explanation of either the entire print stream or a selected portion of the print stream. For more information, see Displaying an Explanation.
