status.i4.v = str_is_enclosed_in_parentheses_c(string.i1a.r

	This routine determines whether or not the passed string is enclosed
	in parentheses.

	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 enclosed in parentheses
	FALSE			string is not enclosed in parentheses

	This function requires the following include files:

	cnsparam_h, cbslib_h
