ckcvg8 DEPRECATED

	ckcvg8(input_buffer.i1a.r, start_index.i2.r, num_chars.i2.r,
	       value.r8.r, error.i2.r)

	This routine decodes the number of decimal ASCII characters
	(in either F or E format) as specified by "num_chars" (1-20) from the
	user's byte buffer, "input_buffer", to an floating value in 'value'.
	The conversion starts at the character position specified by
	"start_index" (first character is position 1).  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	ASCII buffer to convert to floating point value
	start_index	starting character in "buffer" to convert (starts at 1)
	num_chars	number of characters to convert
			(maximum is MAX_FLOAT_CHARS)
	value		returned single precision floating point value
	[error]		returned conversion status
			(OK -> successful conversion,
			 <0 -> character position of first bad character)

	This function requires the following include files:

	clib_h
