	ckcvgc(ibuf.i1a.r, istart.i4.v, nchars.i4.v, value.r4.r, iok.i2.r)

	This routine decodes the number of decimal ASCII characters
	(in either F- or E-format) as specified by NCHARS (1-10) from
	the caller's byte buffer IBUF, starting at the character
	position specified by ISTART, and stores the floating point
	number in VALUE.  IOK is returned as 0 for a successful
	conversion, and negative (character position) for a bad
	character or overflow condition.
