modify_enumerated_strings_c

	status.i4.v = modify_enumerated_strings_c(num_values.i4.v, text.i1a.r,
						  entry_length.i4.v,
						  enumerated_id.i4.v,
						  help_info.sa.r
						  [,values.i4a.r])

	This routine modifies the text strings associated with an
	enumerated data type used by the 'numeric_to_ascii(_c)',
	'ascii_to_numeric(_c)', '(window_)display_value(_c)',
	'(window_)input_value(_c)', and 'winput(_c)' routines.  The
	present values for these strings can be read by a call to
	'get_enumerated_strings'.

	num_values	number of enumerated entries
	text		enumerated text strings
	entry_length	number of characters per enumerated text entry
	enumerated_id	ID number of the enumerated data set which was
			returned by 'set_enumerated_strings_c'  (Passing
			a value of zero for this argument would result in
			the modification of the default enumerated data
			type.)
	help_info	entry by entry help callback information
			(array of HELP_CALLBACK_DATA structures)
			(A value of NULL can be passed for this argument,
			 if no context sensitive entry help is desired.)
	[values]	enumerated numeric values
			(If a value of NULL is passed for this argument,
			 values will be assigned consecutively starting
			 at 0.)
			(default is NULL)

	This function returns ACNET status values as follows:

	CBS_OK			success
	CBS_INVARG		invalid number of values or entry length
	CBS_INVID		invalid enumerated ID
	CBS_NO_SUCH		enumerated data type does not exist
	CBS_MEMFAIL		dynamic memory allocation failure
	CBS_INVSIZ		all passed strings are null strings

	This function requires the following include files:

	cnsparam_h, cns_data_structs_h, cbslib_h, acnet_errors_h

	status = modify_enumerated_strings_c(num_values,(char *) text,
					     entry_length,enumerated_id,
