get_logical_strings

	length.i4.v = get_logical_strings(true_string.i1p.r,
					  false_string.i1p.r)

	This routine returns the text strings associated with the
	logical data type used by the 'numeric_to_ascii(_c)',
	'ascii_to_numeric(_c)', '(window_)display_value(_c)', and
	'(window_)input_value(_c)' routines.  The values for these
	strings can be set by a call to 'set_logical_strings'.
	Since the memory to hold these strings is allocated by this
	routine, the calling program should free this memory when
	it is done using the strings.  If a value of NULL is passed
	for both arguments, only the length of the logical strings
	will be returned.

	true_string	null-terminated ASCII text associated with a
			value of TRUE
	false_string	null-terminated ASCII text associated with a
			value of FALSE

	This function returns status values as follows:

	CBS_MEMFAIL		dynamic memory allocation failure
	otherwise		length of logical test strings

	This function requires the following include files:

	cnsparam_h, cns_data_structs_h, cbslib_h, acnet_errors_h
