    Some little help more with Latex, please

    Hi all:

    Several times already I've tried to write about a function that is "defined" or "undefined" somewhere using LaTex, but I get the following error message: [LaTex Error: Restricted command found (def)]
    Since I can't believe we can't write "defined" using LaTex. what is the way to overcome these restrictions? I tried using " ", enclosing the word in brackets [] , etc., but nothing.

    Thanx for reading

    Here is the answer given by Opalg in another thread:

    [tex]\buildrel \text{d{}ef}\over =[/tex] produces \buildrel \text{d{}ef}\over = .

    That's not the whole story, though. You can fool the MathHelpForum's LaTeX compiler into printing the word "def", but you cannot get it to implement a user-defined control sequence by using the \def command. I assume that is a security precaution, to stop malicious hackers.

    Hello, tonio!

    Several times already I've tried to write about a function that is "defined"
    or "undefined" somewhere using LaTex, but I get the following error message:
    . . [LaTex Error: Restricted command found (def)]

    Since we can't write "defined" using LaTex.
    what is the way to overcome these restrictions?

    Enclose one of the offending letters in a pair of braces.


    While \text{defined} will generate that error message,

    . . \text{de{f}ined} will get us by.


    The censor program here outlaws certain touchy words.
    One of them is the nickname for Richard.
    . . (While Peter, Willy and Johnson are okay!)

    If I want to refer to Mr. Clark of American Bandstand,
    . . I must use: .\text{Di{c}k Clark} . \text{Dick Clark}


    Please . . . do not use this technique to post obscene words.
    You will offend many of us and get yourself banned.
