    I'm wondering how to set my ti 89 to .... " | x does not equal 3, and x does not equal 4 " for any partifular function..... I tried a comma and a "|" still no go...

    ... | x =/= 3 and x =/= 4

    The =/= being the = sign with the slash through it, available through diamond + =

    The and is literally the string "and" which you can type in manually. I prefer to keep a menu item for it. :)
