	This routine returns the subpage labels for a parameter page.

	index_page_name	null terminated ASCII index page name (eg 'M4')
	level_1_text	returned concatenated level 1 subpage text
	level_1_length	length of level 1 text entries
	num_level_1	returned number of level 1 subpages
			(maximum is PARAMPAGE_MAX_LEVEL_1)
	level_2_text	returned concatenated level 2 subpage text
	level_2_length	length of level 2 text entries
	num_level_2	returned number of level 2 subpages
			(maximum is PARAMPAGE_MAX_LEVEL_2)
	level_3_text	returned concatenated level 3 subpage text
	level_3_length	length of level 3 text entries
	num_level_3	returned number of level 3 subpages
			(maximum is PARAMPAGE_MAX_LEVEL_3)
