<h2>Handling Errors</h2>
<a href="index.html">Return to Contents</a>
<p>Whenever a <em>Lexer_Error</em> or <em>Parser_Error</em> is raised it is always accompanied
with a string that contains encoded information about where in the input the error occurred.</p>
<p>Such strings should not be examined directly, but if the <em>Decode</em> function from
<em>Packrat.Errors</em> is used then an array of symbol/position pairs is obtained. Each of those
pairs describes a point in the input where, if the given symbol was successfully found, a more
successful parse would have resulted.</p>
<p>Unfortunately at this time no resumption of lexing or parsing can be done once an error has
occurred.</p>
