</div>
<div>Yes.</div>
<div> \l is pre-defined for the Polish letter l-slash .</div>
<div>You must *not* redefinine it in your Definitions.tex file.</div>

<div>
<div>Alternatively, use \renewcommand{\l}{\v(1)}</div>
<div><br class="">
</div>
<div>But surely this should be \v{1} </div>
<div>unless you have also redefined \v from its default use as an accent-macro.</div>

<div class="">Observation: Upon pressing <return> following the above prompt, the program runs to the end and renders the graph correctly. However I must do this every time I compile my (long) program. This intermediate manual intervention is annoying and
I would like to automate the compilation.</div>

<div>The message is there to stop you from simply redefining macros that already have other uses.</div>
<div>Please respect this, and don’t just choose macro-definitions based entirely upon what you would</div>
<div>like to use. (La)TeX is a shared system. </div>
<div>Respect that other people’s needs can be greater than your own.</div>
