status.i4.v = str_is_bracketed_c(string.i1a.r [,length.i4.v]

	This routine determines whether or not the passed string is enclosed
	in brackets.  It handles "[]", "{}", "<>", and "()" bracket types.

	string		string to check
	[length]	length of string (If a value of zero is passed
			or this argument is defaulted, the length of the
			string will be calculated.)
			(default is 0)
	[options]	check options (not used)

	This function returns status values as follows:

	TRUE			string is bracketed
	FALSE			string is not bracketed

	This function requires the following include files:

	cnsparam_h, cbslib_h

	Related functions:

	str_is_quoted_c, str_remove_brackets_c, str_strip_quotes_c,
	str_find_first_c, str_get_first_c

	C/C++ usage:

	static const char	string[] = "<This string is bracketed.>";
	int	status;
	int	length = 0;
	unsigned int	options = 0;

	status = str_is_bracketed_c(string,length);
