count.i4.v = str_word_count_c(string.i1a.r, length.i4.v,
				      [,delimiters.i1a.r] [,options.u4.v]

	This routine will return the number of words in a string.

	string		string to search
	length		length of string to search (a value of zero
			will result in a search up to a null terminator)
	[delimiters]	null terminated set of delimiter characters
			(default is " \t\n\r\f,;:.")
	[options]	parsing options
			(STR_OPT_NONE -> no options selected (default),
			 STR_OPT_HANDLE_QUOTES -> observe quoted strings)
	[words]		returned word strings
			(default is NULL)

	This function returns status values as follows:

	CBS_INVARG		invalid length passed
	otherwise		number of occurrences of specified character

	This function requires the following include files:

	cnsparam_h, cbslib_h, acnet_errors_h
