I'd lie but no.. I was just trying to clarify what I was looking for. I gave a the code for one of the functions I had written, and then an example of the input the user is giving below, and then tried to describe in more detail what I needed help with...<br>

<p>Hi,</p>
<p>That would not be considered an "example" for at least two reasons. Do you see why?</p>

<br>Here is the code for it.<br><br>(define (plus num1 num2)<br>(+ num1 num2))<br><br>That is childs stuff... Here is where I am having the problem, and please keep in mind I am new to DrRacket...<br>
<br>If my program accepts input such as <br>(plus 13 5)<br><br>I need to parse it so that I know what it is asking for. If It is a left parent, then I need to move on, if it is a right parent, move on to the next character, once i get to the next character I can see it is an alphanumeric character, but then I need to somehow read the whole word, so that I can store that value in a variable so that I can read the next number. If the numbers are single digits, it is easy, because they are only one charater each and read-char works perfect, but I need something like a read-word, or read-number and I can't seem to figure out how to do it. <br>
<br>So really I need to know how do I read the words when there are characters present, and read the whole numbers when there is a number present.</div><p><font color="#500050"><div class="im"><br><br>On 9 November 2010 15:00, John Clements <<a href="mailto:clements@brinckerhoff.org" target="_blank">clements@brinckerhoff.org</a>> wrote:<br>
