# File Definitions
Read Time: 1 minute(s)
# Description
File definition records contain information that is used when formatting reports. For example, should the key field of a file be left or right justified, and how wide a column should it occupy. You can also define sublist codes to tell the system that a particular field is multivalued.
This section starts with a review of file definition records and discusses how the content of these records can affect the output from jQL commands - particularly with reference to sublists.
# Record Structure
The fields of a file definition record that affect jQL reports are:
| Field 7 | Conversion code for key, if required. For date, time, etc. |
| Field 8 | V code to notify a multivalued (sublist) field, if required. See Sublists - V Code. |
| Field 9 | Justification for key. Can be one of the following (see Data Definition Records): |
| Field 10 | Column width for key. Default is 14 characters. Also see JBCIDLEN. |
