 Hence, we can utilise \texttt{sys.m}'s inbuilt \texttt{PATH} constant — as we saw on page \pageref{sys.m} — by simply referencing it using an arrow thusly: \texttt{Sys->PATH}; this is the syntax we are required to use whenever we wish to refer to a constant or function within a different module.
 
-Thenceforth, the \texttt{sys} variable will be in the possession of a \texttt{Sys} instance, whereupon we may use it to access \texttt{sys.m} in-built functions, which will be needed on line 16, whereon we refer to the \texttt{print} function of \texttt{Sys}.
+Thenceforth, the \texttt{sys} variable will be in the possession of a \texttt{Sys} instance, whereupon we may use it to access \texttt{sys.m} in-built functions, which will be needed on line 16, whereon we refer to the \texttt{print} function of \texttt{Sys}. This particular function, as we ascertained previously, takes a string as its argument, which we here supply as \texttt{"Hello, World!"}. The trailing \texttt{\textbackslash n} is not printed verbatim, as it is a so-called \textit{escape character}, which, in this instance, creates a new line; had this been left out, our printed text would appear in a rather inept position, behind the \texttt{\%} symbol of our shell instead of being located on its own line.
