status.i4.v = wn_text_size(size.i4.r)

	status.i4.v = wn_text_size_c(size.i4.v)

	This routine sets the current text size for graphical windows.

	size		text size (Note: Valid values are from WN_TEXT_MIN_SIZE
			to WN_TEXT_MAX_SIZE.)  (If a value of CLIB_DEFAULT_ARG
			is passed for this argument, the present size will
			simply be returned to the caller.)

	This function returns status values as follows:

	CBS_INVARG		invalid text size
	otherwise		previous text size setting

	This function requires the following include files:

	clib_h, cbslib_h, acnet_errors_h
