moveby(source_buffer.g.v, source_index.i2.r, dest_buffer.g.v,
	       dest_index.i2.r, num_bytes.i2.r [,nodescr.i1.r])

	This routine copies a block of bytes from one buffer to another.

	source_buffer	buffer to copy from
	source_index	byte array index in 'source_buffer' to start
			copying from (starts at 1)
	dest_buffer	buffer to copy to
	dest_index	byte array index in 'dest_buffer' to start
			copying to (starts at 1)
	num_bytes	number of bytes to copy
	[nodescr]	unused retained for compatibility.
