status.i4.v = str_nonblank_length_c(string.i1a.r, maximum_length.i4.v)

	This routine returns the length of a string excluding trailing

	string		string to check
	maximum_length	maximum allowable return length
			(Note: If a value of STR_NO_LIMIT is passed,
			 maximum length will be set to infinity for a
			 C string or the descriptor length field value
			 for a string passed by descriptor.)

	This function returns status values as follows:

	nonblank length of the string

	This function requires the following include files:

	int	maximum_length = STR_NO_LIMIT;

	status = str_nonblank_length_c(string,maximum_length);
