cve8

	cve8(value.r8.v, nchars.i4.v, outbuf.i1a.r, start.i4.v)

	This routine will convert a double precision floating point value
	in the user's variable 'value' into 'nchars' E-format characters.
	The characters will be placed in the user's byte buffer, 'outbuf',
	starting at the character position specified by 'start'
	(first character is position 1).
