View source for Trace (XmlDoc/XmlNode subroutine)

{{Template:XmlDoc/XmlNode:Trace subtitle}}
<var>Trace</var> displays an <var>XmlDoc</var> subtree in a readable form, useful for debugging, for example.  <var>Trace</var> is identical to <var>[[Print (XmlDoc/XmlNode subroutine)|Print]]</var>, except the result is sent to the currently selected trace stream.  That stream can be the user's standard output, the <var class="product">Model 204</var> audit trail, an internal trace table, or a combination of these (as described for the <var class="product">User Language</var> <var>[[Trace statement|Trace]]</var> statement).  Also, the default indentation for <var>Trace</var> is one space, while the default for the <var>Print</var> method is three.

The default <var>Trace</var> statement stream is the terminal, so unless you reset the [[ULTRACE parameter|ULTRACE]] parameter to select another stream, <var>Trace</var> is the same as using <var>Print</var>.
