<b>Function</b>
<dd>
Defines a combo box selection field.
<p>
<dt>
<b>Syntax</b>
<dd>
<tt>dlgComboBox(string array[], int &Selected) [ <i>statement</i> ]</tt>
<p>
<dt>
<b>Description</b>
<dd>
The <tt>dlgComboBox</tt> statement defines a combo box selection field with the contents
of the given <tt>array</tt>.
<p>
<tt>Selected</tt> reflects the index of the selected combo box entry. The first entry has index <tt>0</tt>.
<p>
Each element of <tt>array</tt> defines the contents of one entry in the combo box.
None of the strings in <tt>array</tt> may be empty (if there is an empty string,
all strings after and including that one will be dropped).
<p>
The optional <tt>statement</tt> is executed whenever the selection in the <tt>dlgComboBox</tt> changes.<br>
Before the <tt>statement</tt> is executed, all variables that have been used with dialog objects
are updated to their current values, and any changes made to these variables inside the
<tt>statement</tt> will be reflected in the dialog when the statement returns.
<p>
If the initial value of <tt>Selected</tt> is outside the range of the <tt>array</tt>
indexes, it is set to <tt>0</tt>.
