LaTeX macros ending in numbers

By admin | February 13, 2016

Only letters are directly permitted in macro names, but by using csname to create definitions along with a variable command, we can simulate them.

First, define the macros with numbers using \csname:

\expandafter\def\csname xR1\endcsname{-3}
\expandafter\def\csname xR2\endcsname{9}

Now, create a command which takes in one variable argument, and simply expands it to call the appropriate macro (“xR” + variable) defined above.

\newcommand{\xR}[1]{\expandafter\csname xR#1\endcsname}

And to use the macros:

The first is \xR1 and the second is \xR2.
