Final answer:
The Master File that stores one record for every display column in Chronicles is the Field Definition File. This file contains information about each display column in Chronicles, such as the name, length, data type, and format.
Step-by-step explanation:
The Master File that stores one record for every display column in Chronicles is the Field Definition File. This file contains information about each display column in Chronicles, such as the name, length, data type, and format.
For example, let's say we have a display column called 'Product Name' in Chronicles. The Field Definition File would have a record for this column with details like the name being 'Product Name', length being 50 characters, data type being alphanumeric, and format being plain text.
By maintaining a separate Field Definition File, Chronicles can efficiently manage and organize the display columns, making it easier to retrieve and present data to users.
