Forgot to mention that in all cases which I recall of the use of "M" for kilohms, "megohms" was actually spelled out. Also seen occasionally as "megaohms". But that's the confidence test. Many things will have at least one resistor over 1MOhm, so if it's spelled out then all the Ms can safely be assumed to be kilohms. Fred -- <>< -- Outgoing checked by Norton AV
