  <a name="1204932"> </a><font size=2  face="Verdana, Arial, Helvetica, sans-serif">Procedures can be defined to enable new commands to be created. The syntax for defining a procedure is:</font>
</p>


<a name="1204935"> </a><font size=2 face=Courier><strong>proc <font size=2 face=Courier><strong><em>name</em></strong></font> <font size=2 face=Courier><strong><em>local_variables_list</em></strong></font> { <font size=2 face=Courier><strong><em>command_list</em></strong></font> }<br></strong></font>



<p>
  <a name="1204936"> </a><font size=2  face="Verdana, Arial, Helvetica, sans-serif">This defines a procedure called <font size=2 face=Courier><strong><em>name</em></strong></font> which is equivalent to <font size=2 face=Courier><strong><em>command_list</em></strong></font>. <font size=2 face=Courier><strong><em>local_variables_list</em></strong></font> is a sequence of variable declarations that declare variables that are local to the procedure. A global variable of the same name as a local variable cannot be accessed locally. Variable declarations in the list are separated by semicolons (;) and each declaration consists of the variable name followed by "<font size=2 face=Courier><strong>=</strong></font>" followed by an integer initial value. For example:</font>

<a name="1204937"> </a><font size=2 face=Courier><strong>proc foobar<br>
