status.i4.v = wn_set_max_tick_mark_lengths_c(max_minor_tick_length.i4.v,

	This routine sets maximum lengths of tick marks for future
	graphics calls using the "wn_xxxx" routines.

	max_minor_tick_length	maximum minor tick mark length in pixels
	max_major_tick_length	maximum minor tick mark length in pixels

	This function returns status values as follows:

	OK			success
	CBS_INVARG		negative length or minor tick mark length
				is greater than the major tick length

	This function requires the following include files:

	cnsparam_h, cbslib_h, acnet_errors_h

	wn_text_size(_c), wn_flush, wn_multitrace_axis_label_c,
	wn_multitrace_grid_c, wn_multitrace_grid_pixel_c,

	C/C++ usage:

	int	status;
	int	max_minor_tick_length = 20;
	int	max_major_tick_length = 40;

	status = wn_set_max_tick_mark_lengths_c(max_minor_tick_length,
