    • Note in this example.

    • You can use the escape sequence \" to insert a quotation mark as a character, instead of as a formatting character.

    • You can embed functions within functions,as in QUOTE(UPPER(ultext)).

    • Alpha Anywhere has more than 130 character manipulation functions that can do anything with text.
