Is there any way I can define a variable in LaTeX?

latex, variables

Solution

add the following to you preamble:

\newcommand{\newCommandName}{text to insert}

Then you can just use `\newCommandName{}` in the text

For more info on `\newcommand`, see e.g. wikibooks

Example:

\documentclass{article}
\newcommand\x{30}
\begin{document}
\x
\end{document}

Output:

30

Problem

In LaTeX, how can I define a string variable whose content is used instead of the variable in the compiled PDF? Let's say I'm writing a tech doc on a software and I want to define the package name in the preamble or somewhere so that if its name changes, I don't have to replace it in a lot of places but only in one place.
