<h4><a name="wsajacl"></a>The Jacl scripting language</h4>
|
||
|
|
|
||
|
|
<p>Jacl is an alternate implementation of TCL, and is written entirely in Java code.</p>
|
||
|
|
|
||
|
|
The basic syntax for a Jacl command is:
|
||
|
|
|
||
|
|
<pre>Command arg1 arg2 arg3 ...</pre>
|
||
|
|
|
||
|
|
<p>The command is either the name of a built-in command or a Jacl procedure. For example:</p>
|
||
|
|
|
||
|
|
<pre>puts stdout {Hello, world!}</pre>
|
||
|
|
|
||
|
|
<p>This example demonstrates the <tt>puts</tt> command, which takes two arguments: an I/O stream identifier (stdout) and a string (Hello, world!). The <tt>puts</tt> command writes the string and a trailing new line character to the I/O stream. In Jacl, the command interprets the specified arguments. The use of stdout as a name is a convention employed by puts and the other I/O commands. Use stderr to identify the standard error output, and use stdin to identify the standard input.</p>
