Thread: 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
Tonio

Here is the answer given by Opalg in another thread:

You can fool the system into accepting a reserved word like def by disguising it, splitting it up with a pair of braces.

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

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} .


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