ckcvn DEPRECATED

	ckcvn(input_buffer.i1a.r, start_index.i2.r, num_chars.i2.r, value.i2.r,
	      error.i2.r, radix.i2.r)

	This routine will convert the number of characters specified by
	"num_chars" from the user's byte buffer, "input_buffer", to an
	integer value in "value".  The conversion is made using the radix
	"radix".  The conversion starts at the character position specified
	by "start_index" (first character is position 1).  If a null character
	is encountered, the conversion will be terminated.  If a valid
	conversion has been performed, the value of "error" is returned as zero.
	Otherwise, the position of the first 'bad' character is returned in
	"error" as a negative value.

	input_buffer	input ASCII buffer
	start_index	offset index into the ASCII buffer to begin conversion
			starting at 1
	num_chars	number of ASCII characters to use
	value		returned value
	error		returned conversion status
			(0 -> successful conversion,
			 <0 -> invalid character at this position)
	radix		radix to use for the conversion
			(values should be between 2 and 36)

	This function requires the following include files:

	clib_h

	Related functions:

	ascii_to_numeric(_c), cvi, numeric_to_ascii(_c), cvn

	C/C++ usage:

	char	input_buffer[NUM_CHARS];
	short	start_index = 1;
	short	num_chars = NUM_CHARS;
	short	value;
	short	error;

	ckcvn(input_buffer,&start_index,&num_chars,&value,&error,&radix);
