+/* SUMMARY
+/*	token list search operators
+/* SYNOPSIS
+/*	#include <tok822.h>
+/*
+/*	TOK822	*tok822_find_type(head, type)
+/*	TOK822	*head;

+/* DESCRIPTION
+/*	This module implements token list search operations.
+/*
+/*	tok822_find_type() searches a list of tokens for the first
+/*	instance of the specified token type. The result is the
+/*	found token or a null pointer when the search failed.
+/*
+/*	tok822_rfind_type() searches a list of tokens in reverse direction
+/*	for the first instance of the specified token type. The result
+/*	is the found token or a null pointer when the search failed.
