Re: What if the symbol doesn't exist?
Vinh, Script E The symbols available are given in the palette menu> File > Palettes > 9 CompleteCharacters. Script E is in Letters>Script You can copy it into your notebook by clicking on it; also, when the curser over it you will see two ways of typing it in given in the bottom bar of the patette window: esc scE esc, and \[ScriptCapitalE]. Making Subscript[x,y] into a symbol I'll do a little more. << Utilities`Notation` A panel will appear. Use this to construct Symbolize[< 2D form of Subscript[x,_]>] For information about this technique look up in the Help Browser, Add-ons > Extras > Utilities > Notation Package -- Allan --------------------- Allan Hayes Mathematica Training and Consulting Leicester UK www.haystack.demon.co.uk hay at haystack.demon.co.uk Voice: +44 (0)116 271 4198 Fax: +44 (0)870 164 0565 "Vinh N.
