# Master dictionary file

The master dictionary file contains
commands, Procs, Macros, Menus, connectives, default attribute-defining
items, file-defining items (both local (D-pointers) and synonym (Q-pointers))
and cataloged FlashBASIC programs.

## Description

There is one master
dictionary file for each account. When a new account is
created, a standard set of vocabulary items are copied into the new
account’s master dictionary. File-defining items (D-pointers) and
synonym-defining items (Q-pointers) are two types of file pointers
found in a master dictionary. File-defining items point to files within
the current account. Synonym-defining items can point to files either
within the current account or within other accounts.

Attributes
2 and 3 of file-defining items in an account master dictionary contain
the base FID and modulo respectively of the file dictionary to which
the item points.

The usage and definition of the attributes
in the master dictionary file-defining item are described in [File-defining items](https://d3codex.com/definitions/file-defining-items/).

The Update processor
displays the contents of attributes 1 through 10 (with default values
in place for new accounts). To add to the contents of attribute 13,
move the cursor to the end of attribute 10, press ENTER three times
and add the new modulo surrounded by parentheses to resize the master
dictionary file in attribute 13.
