Verbatim going beyond borders

Question

I use \begin{verbatim} and \end{verbatim} and have enclosed a Fortran code within it. (I am not using listing for a reason).

However, Verbatim is crossing the boundaries.

How do I fix this?

My packages list is:

\documentclass[12pt,a4paper]{article}
\usepackage[latin3]{inputenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage{listings}
\usepackage[left=2cm,right=2cm,top=2cm,bottom=2cm]{geometry}

Answer 1

You are loading the listings package hence use key breaklines=true and \begin{lstlisting}...\end{lstlisting}.

\documentclass{article}
\usepackage{xcolor,listings}
\lstloadlanguages{[LaTeX]TeX, [primitive]TeX,fortran}
\lstset{language={[LaTeX]TeX},
      escapeinside={{(*@}{@*)}}, 
       gobble=0,
       stepnumber=1,numbersep=5pt, 
       numberstyle={\footnotesize\color{gray}},%firstnumber=last,
      breaklines=true,
      framesep=5pt,
      basicstyle=\small\ttfamily,
      showstringspaces=false,
      keywordstyle=\ttfamily\textcolor{blue},
      stringstyle=\color{orange},
      commentstyle=\color{black},
      rulecolor=\color{gray!10},
      breakatwhitespace=true,
      showspaces=false,  % shows spacing symbol
      backgroundcolor=\color{gray!15}}
\begin{document}

\begin{lstlisting}
a very long and totruous path which you can check to see if it breaks and where at the end of the line
\end{lstlisting}

\end{document}
