The Script adventure game language is an object-oriented language with a Lisp-like syntax. It is compiled by the sc compiler into the pseudo-code which is used by the interpreter, sci.

We will begin our discussion of the language with its basic Lisp-like characteristics, then go on to the object-oriented parts of the language.
 
  
As is Lisp, Script is based on parenthesized expressions which return values. An expression is of the form
+
&nbsp;
  
<div class="CodeBlockHeader">Code:</div>
+
<span style="float: left"><span class="Inactive">&lt; Previous: </span></span><span style="float: right">[[The Script Programming Language/Introduction|Next: Introduction &gt;]]</span>
<syntaxhighlight lang="sci">
 
      (procedure [parameter parameter ...]).</syntaxhighlight>
 
  
The parameters to a procedure may themselves be expressions to be evaluated, and may be nested until you lose track of the parentheses.
+
&nbsp;
  
Unlike Lisp, the procedure itself may NOT be the result of an evaluation. An example of an expression is

+
[[Category:Scripting]]
<div class="CodeBlockHeader">Code:</div>
 
<syntaxhighlight lang="sci">
 
      (+ (- y 2) (/ x 3))</syntaxhighlight>
 
 
 
which would be written in infix notation as
 
 
 
<div class="CodeBlockHeader">Code:</div>
 
<syntaxhighlight lang="sci">
 
      (y - 2) + (x / 3).</syntaxhighlight>
 
 
 
All expressions are guaranteed to be evaluated from left to right. Thus,
 
<div class="CodeBlockHeader">Code:</div>
 
<syntaxhighlight lang="sci">
 
      (= x 4)
 
      (= y (/ (+= x 4) (/= x 2)))</syntaxhighlight>
 
 
 
will result in y = 2 and x = 4.
 
 
 
Comments in Script begin with a semi-colon, ';', and continue to the end of the line.
