One of the features of the Lattice 4.0 compiler is that it generates the optimal '010 instructions where possible. This make increase your mileage another couple of percent. In general the '010 does not speed you up too much. --Chuck McManis uucp: {anywhere}!sun!cmcmanis BIX: cmcmanis ARPAnet: cmcmanis@sun.com These opinions are my own and no one elses, but you knew that didn't you.
