intro_td

	Table Devices can be read and set using routines:

	'td_build(_c)'		build a list of table and slot specifications
	'td_read'		read a list previously setup with td_build
	'td_set(_c)'		set a list previously setup with td_build
	'td_cancel'		delete a list previously setup with td_build
	'td_read_one(_c)'	read a single table's slot values 
	'td_set_one(_c)'	set a single table's slot values
	'td_query'		returns information about a rampcard's table
	
	When giving table specifications one use defined constants in 
	the 'diolib' include files (search for "table devices").
	
	Presently, one can use the database scaling services for the
	dependent part of slots only.  The same scaling (PDB) is applied
	to all slots in the device.

	See also 'intro_c465' and 'intro_dio'.

	These functions require the following include files:

	diolib_h
