FIELD Command as Used in this Example

In the FIELD command, the START and LENGTH parameters specify the location of the field in the record to be processed. START indicates the starting byte position, and LENGTH specifies the number of bytes in the field.

Because a field can be located independently within the data and on the printed page, more than one page definition or page format can be created for the same data file, each specifying different mapping of the data to the output pages.
