An Editor Interface is a number of attributes that control how the Hex Editor Window appears (see Using the Hex Editor) and how data is interpreted in the window. The Editor Interface includes the Font, Addresses, Width, Group By, Division Lines, Areas, Character Set, Highlight, Ruler, and Endian of the window. Edit the current interfaces from the View Menu, or from the Tool Bars. By default, all files and processes that are open share one Editor Interface, and all drives share another. Modifying an option for one window modifies that option for all windows that use that interface. Any changes to the interface are automatically saved when 010 Editor exits, so the interface will appear the same the next time the program loads.

Multiple interfaces can be generated for files and assigned automatically when a file loads. For example, 010 Editor can be configured to always open a file with a certain file extension in Big Endian mode, or with the EBCDIC character set. To create new interfaces, use the 'View > Interfaces' menu (see the View Menu for more information), or the Interface Options dialog (see Interface Options dialog). The 'View > Interfaces' menu contains a list of all available Editor Interfaces and a checkmark will be placed beside the currently active interface.

The following list indicates all attributes that are stored with the Editor Interface:

• Font - Controls the font type, size, and style that are used in the editor.

• Addresses - Controls whether the addresses on the left side of the editor are displayed in hex format, decimal format, octal format, or whether the current line number is displayed.

• Width - Specifies how many bytes are displayed per row in the editor. Select Auto to allow the program to choose the maximum number of bytes based on the width of the window.

• Group By - Sets how many bytes are grouped together in the editor (the default is one).

• Division Lines - 010 Editor can draw a set of lines on the Hex Editor Window to visualize how different bytes are grouped together. There are two types of lines that can be drawn: Division Lines and Sector Lines. By default, a division line is drawn every 4 bytes in a light-gray color and a sector line is drawn for each sector in a dark-gray color when editing hard drives. See the View Menu for more information on Division Lines.

• Left Area - Controls which numeric format is displayed in the left area of the editor (Hex, Char, Octal, Binary, or Decimal).

• Right Area - Controls which numeric format is displayed in the right area of the editor (Hex, Char, Octal, Binary, Decimal, or Hide).

• Character Set - Sets which character set is used to display data in a character area (ASCII, ASCII+OEM, ASCII+ANSI, EBCDIC, UNICODE, Macintosh, or various international character sets).

• Highlight - Controls which bytes are highlighted in the editor. A number of highlighting schemes are available by default, but more can be generated through the Highlight Options dialog.

• Endian - Controls which byte-ordering is used for the current editor (see Introduction to Byte Ordering).

• Ruler - Specifies whether the Ruler is displayed at the top of the Hex Editor Window.

See the View Menu for more details about each option.
