+ * Steps performed:
+ *
+ *   1)  Create the dialog with all the windows we will need
+ *	 later.  This is done by calling vardlg_build() from
+ *	 gic_prompter().
+ *
+ *   2)  Run the dialog from within gic_prompter().  If the return
+ *	 value of the dialog is -1 or IDCANCEL, return an error.
+ *	 Otherwise, return success.
+ *
+ *   3)  From within the dialog initialization code, call
+ *	 vardlg_config(), which will:
+ *
+ *	a)  Set all the label strings in all the entry labels and
+ *	    the banner.
+ *
+ *	b)  Set the maximum input lengths on the entry fields.
+ *
+ *	c)  Calculate the size of the text used within the banner.
+ *
+ *	d)  Calculate the longest string of text used as a label.
+ *
+ *	e)  Resize each label and each entry within the dialog
+ *	    to "look nice."
+ *
+ *	f)  Place the OK and perhaps the Cancel buttons at the bottom
+ *	    of the dialog.
+ *
+ *   4)  When the OK button is clicked, copy all the values from the
+ *	 input fields and store them in the pointers we are given.
+ *	 Also, set the actual lengths to what we collected from the
+ *	 entries.  Finally, call EndDialog(IDOK) to end the dialog.
