I want my two dollars:


However, all I get is:

! TeX capacity exceeded, sorry [input stack size=5000].
\font@name ->
l.3 \edef\twodollars{\$

Is it possible to use \edef with a value that includes a dollar sign?

Why not just use \def\twodollars{\$2}? –  Werner Nov 30 '11 at 5:07
@Werner: in the application the "2" is a macro \twoOrThree, and I want to use the value \twoOrThree has at the time of \twodollars definition, rather than the value at a later expansion of \twodollars. –  Jack Schmidt Nov 30 '11 at 5:10
Also, the dollar sign just has to look like a dollar sign when \twodollars is expanded in plain horizontal mode text. I didn't see a "\textdollarsign" like for underscore. –  Jack Schmidt Nov 30 '11 at 5:11

\edef\twodollars{\string$2} \twodollars

\string changes the category code for $ to 12 (other).

Works like a charm, even in the convoluted mess of my real application. Thanks! –  Jack Schmidt Nov 30 '11 at 5:19
@JackSchmidt: If you need this more often, consider defining a macro for the dollar. For example, the newverbs package allows for \Verbdef\dollar|$|, which also works for other special characters including %, where \string does not work. –  Martin Scharrer Dec 1 '11 at 8:59

The correct way is to say
