There are two ways to go about this, and which is cleaner is up to you:

	$ BELL = "^G"	!Enter the <BEL> (^G) character using SPECINS
			!in EDT (<GOLD>7<GOLD><KP3>) or similar method
			!in any other editor.  This does cause you grief
			!when you type the command file, but it's easy.


	$ BELL = " "	!This defines BELL as a character symbol.
	$ BELL[0,8] = 7	!This replaces the first eight bits of the symbol
			!with the value seven.  Now BELL contains an ASCII bell.

The same techniques can be used to create local (or global) symbols containing
the <ESC> or <CSI> characters, and those can be used to build ANSI escape 
sequences.
