H - Hexadecimal

Toggles the Editor's hexadecimal display format. When the Editor is in hexadecimal format, you can enter characters in hex as well as viewing them.

Syntax

H

Control Character Display

This command is most useful when you are editing items that contain control characters. The Editor displays control characters as a period (.) when in ASCII display format, so you cannot read them.

Status Messages

The Editor displays a message of either HEX ON  or HEX OFF, depending on the state of the display.

When H is ON, all commands that use strings must be entered as hexadecimal characters.

The initial state of the switch is OFF.

Example

View an item with both periods and ASCII control characters in hexadecimal format. The control characters in this example item are CTRL+D, CTRL+O, and CTRL+T (X'04', X'0F', and X'14'), the last three characters in attribute 9. The period is the tenth character in attribute 7 (X'2E').
